November Work: Cutting Down the Meadows

Last week, I performed what has become for me a ‘rite of November’: cutting down the meadows at our cottage on Lake Muskoka, a few hours north of Toronto. I have to admit, it isn’t my favourite chore of the year, though I acknowledge I don’t actually have a lot of “chores” up there, given the naturalistic way I garden. But it’s definitely the most labour-intensive – amidst the least pleasant weather conditions of autumn, as it usually turns out. This year it was blowing a gale as I assembled my wardrobe and tools:  hedge shears, rake, cart, bundling cloth and ropes, rubber boots, extra layers under my waterproof jacket and fleece band to keep my ears warm. I started out with the big bluestem (Andropogon gerardii), the tallest of my prairie grasses, at 7 feet with its turkey-foot flowers. Considering it’s growing in shallow soil atop the ancient rock of the Canadian Precambrian shield, rather than the deep loam of the tallgrass prairie where its roots can extend far down, I think it’s rather happy at the cottage, and I took a selfie of us together before I chopped off its head!

Since my meadows and beds likely measure only about 1600 square feet or so, it’s not a lot to hand-cut with the hedge shears. People wonder why I don’t use a string trimmer, but I find that holding the weight of a trimmer just above ground is harder on my back than bending over and chopping the stems manually. I understand you can buy a harness for the trimmer, so that might be an improvement – but there’s something hypnotically satisfying about working with the shears.

As I work, I rake and pile the stems into windrows near the cart where I’ll eventually pack them up into bundles to carry by hand up the hill behind the cottage to a place out of sight where they can break down.

If I don’t cut the meadows, the heavy snows of winter will soon bend down the grasses and forb stems, but the thatch that accumulates makes it less attractive for self-seeding wildflowers and daffodils emerging in spring. So if I want the scene below in mid-summer, it pays to prepare for it by cutting old growth.

And if I leave the switch grass (Panicum virgatum) standing after it turns colour in fall….

…. it will look like this in May.

So I remove all the above ground growth in November.

And if I’m travelling during this late autumn window (as we have on a few occasions), the daffodils will still come up in the meadow the following spring, but it’s a bit of a struggle.

In short, if I want this…..

I could hold off on the cutting until late winter or very early spring, when the ground is still frozen (as I do in my city meadow), but timing doesn’t always work that well up here and a fast thaw means I’m cutting on mucky soil. And since most of the seed-eating birds have flown south and those that remain seem adept at picking up seed from the ground, I’m happy to clear out this…..

Beyond the chores of this month, I love the varied browns of November. I’ve even blogged about Beguiling Brown in the Garden. And I enjoy inspecting all the seedheads as the plants complete their life cycles. Plants like showy goldenrod (Solidago speciosa), its white panicled seedheads shown below alongside the charcoal autumn foliage of false indigo (Baptisia australis). (Incidentally, though these plants flower at the opposite ends of summer, they’re among the best for bumble bee foraging.)

Seedheads-Solidago speciosa & Baptisia australis-November

Here is the candelabra-like seedhead of culver’s root (Veronicastrum virginicum) with the ubiquitous button-like seedheads of wild beebalm (Monarda fistulosa).

Seedheads-Veronicastrum virginicum & Monarda fistulosa-November

Those seedheads above, of course, are proof that the attractive summer flowers, shown below, attracted the pollination services of the appropriate wild bees.

Flowers-Veronicastrum virginicum & Monarda fistulosa-summer

And the late summer-autumn season has also allowed the various grasses to shine, below, including – apart from the big bluestem – Indian grass (Sorghastrum nutans) and switch grass (Panicum virgatum).

Big Bluestem & Indian grass-Lake Muskoka

November is the perfect time for dormant seeding native wildflowers, so as I’m chopping the stems, I also do some fast sowing into the meadows, using my boot toe to kick little bare spots into the soil, then grinding some of the seeds just below the surface, while leaving others exposed. I do this with New York ironweed (Vernonia noveboracensis), below.

Fall seeding-New York Ironweed-Vernonia-Lake Muskoka

Chopping, raking, piling, carrying. Chopping, raking, piling, carrying. After a good day-and-a-half in blustery wind and intermittent cold rain, I manage to take 8 tied bundles of stems up the back hill to a spot on top of the pile of blast rock that was cleared when we built our home here on this waterbound peninsula 16 years ago. In time, the vegetation will decompose amidst the staghorn sumac pioneers and create a more complex meadow planting here.Compost pile-Lake Muskoka

Finally, as I finish washing out the cart, coiling the garden hoses, cleaning my tools, bringing everything indoors and preparing to drive back to the city in the waning light of the third day, I gather up a handful of the stems I’ve put aside in my cutting. Because apart from enjoying vases filled with summer flowers in July…..

Bouquet-July meadow flowers-Lake Muskoka

….. it feels virtuous, somehow, to accord these plants the same respect in November.

Bouquet-November meadow seedheads-Lake Muskoka

To capture a little of the atmosphere of what it’s like to perform this task in November, I’ve made a short video to enjoy here. (Please excuse the wind – it was impossible to find quiet moments.) The good news? My back and I are still on speaking terms!

 

Monkshood & Snakeroot for a Fall Finale

What a luscious October afternoon! I looked out my back window and was drawn, as I always am this time in autumn, to the furthest corner of the garden, where a little fall scene unfolds that I treasure more because it’s a secret. Want to see it?  Let’s take a little stroll past the messy pots on the deck with their various sedums and swishing sideoats grama (Bouteloua curtipendula) out into the garden past the table and chairs that haven’t been used since… when? August?

Janet Davis-garden-autumn

Keep going to where the lovely chartreuse Tiger Eyes sumac (Rhus typhina ‘Bailtiger’) is currently doing its Hollywood star thing in brilliant apricot…..

Tiger Eye Sumac-Rhus typhina 'Bailtiger'-fall color

But what’s this scene, just behind it?

Tiger Eye Sumac-snakeroot-monkshood-Janet Davis

Yes, two stalwarts of the autumn garden – and I mean autumn, fall, October!  Autumn monkshood (Aconitum carmichaelii ‘Arendsii’) and autumn snakeroot (Actaea simplex), aka fall bugbane. Each year, they flower at the same time, and enjoy identical conditions in my garden, i.e. the most moisture-retentive soil (lowest corner of the garden by a few inches), with reasonable midday sunshine but dappled shade a good portion of the day. The fragrance of the snakeroot is fabulous, something a little soft and incense-like, or reminiscent of talcum powder (in the nicest way).  Colour-wise, I love blue and white, from the earliest anemones-with-scilla in April to this shimmering, assertive finale.

Janet Davis-Actaea simplex & Aconitum carmichaelii 'Arendsii'

And did I mention pollinators? As in bumble bees of different species, honey bees……

……hover flies…..

….and paper wasps, below, as well as ants and cucumber beetles.

Monkshood is deadly poisonous, but its pollen seems to be an attraction for bumble bees and honey bees once the asters have finished up.

Bombus-Fall Monkshood-Aconitum carmichaelii 'Arendsii'

Finally, do note that the snakeroot is not any of those fancy-schmancy dark-leaved cultivars like ‘Brunette’, but the straight species with plain-Jane-green-foliage,. And that it used to be called Cimicifuga, but the gene sequencers have now moved it into Actaea.  It is a lovely plant and should be used much, much more.

Festival Theatre Garden – Stratford

For the first time in more than 20 years, I spent a few days this month at Ontario’s venerable Stratford Festival. (For the record, we saw Guys & Dolls – highly recommended; HMS Pinafore – fun Gilbert & Sullivan; and The Changeling – read a story précis before seeing!).  We walked along the Avon River on our way to the first play, and I thought for the thousandth time how lovely our native wildflowers look in early autumn. This is heath aster (Symphyotrichum ericoides) with lots of bees!

Symphyotrichum ericoides-Heath aster-Avon River-Stratford

The entire countryside around Stratford is gorgeous in September, with rows of tall corn and nearly-ripe pumpkins filling the fields near Highway 7 as you drive in. In fact, it’s one of the beautiful farms in the area that renowned singer Loreena McKennitt calls home. I interviewed her in Stratford for a story I proposed and wrote for Chatelaine Gardens! magazine some 21 years ago.

Loreena McKennitt-1997-Chatelaine Gardens

A few summers later, I visited Stratford to photograph the new garden at the Festival Theatre for a story I proposed and wrote for Landscape Trades Magazine.  Having opened in 1997, it was under the expert care of Stratford Festival head gardener Harry Jongerden, who is now Executive Director of the Toronto Botanical Garden.

Landscape Trades-1999-Festival Theatre Garden

Returning to Stratford this month, I was excited to see how the garden had weathered over the past few decades and, especially, to see what was in bloom in the first week of autumn.  Since my magazine story was published such a long time ago, I’ll take the liberty of quoting it from time to time here, as we tour the plants – like this lovely Japanese anemone (Anemone x hybrida ‘Whirlwind’).

Anemone x hybrida 'Whirlwind' - Festival Theatre

***********

Two hours west of Toronto, on a hill overlooking the Avon River, sits the Festival Theatre, main stage and head office for Canada’s renowned Stratford Festival. Since its first production in 1953, a play directed by Tyrone Guthrie, starting Alec Guinness and mounted under a canvas tent, the Festival has enjoyed wide critical acclaim, and Stratford has become a mecca for theatre lovers — and garden lovers. Isn’t this swamp hibiscus (H. moscheutos) spectacular?

Hibiscus moscheutos-Swamp hibiscus-Festival Theatre Garden

In 1997, the Festival Theatre (one of three in Stratford used by the festival) underwent a major renewal under the direction of Toronto architect Thomas Payne, then of KPMB Architects, now with Thomas Payne Architect.  Trained at Yale and Princeton and one-time protégé of Barton Myers, Payne’s work includes the ethereal Fields Institute for Mathematics at the University of Toronto, a new home for the National Ballet of Canada, the much celebrated Tanenbaum Sculpture Gallery at the Art Gallery of Ontario (AGO), the restoration of the Goodman Theatre in Chicago and the Young Theatre for the Performing Arts (Soulpepper). His work at Stratford involved indoor renovations such as changing the rake of the theatre floor to create more spacious seating; adding technical gutters and an acoustical canopy; and renovating the lobby.  And with the collaboration of Toronto landscape designer Neil Turnbull, Payne created The Arthur Meighen Gardens, named for Canada’s ninth prime minister and funded, in large part, by the Meighen family foundation. It  was a new garden that was as rich in theatrical allusion as it was in stone and plants.

Arthur Meighen Gardens-Festival Theatre

A horseshoe-shaped entrance driveway lined with concrete arbor columns, each one draped with a clematis in early summer – or morning glories in late summer — encircles the garden.  “At night,” Payne told me then, they look like Noguchi lamps.”

Anemone x hybrida & Festival Theatre Lights

The columns, each dedicated to a local benefactor, are clothed in a sock of inexpensive, water-repellent canvas symbolizing the canvas roof of the first performance tent.

Ipomoea tricolor-Morning glory-Festival Theatre

The garden is a fragrant, romantic tumble of perennials, designed to be in bloom as the curtain rises in mid-April, and still have something in flower for October’s final curtain call.  In late September, ligularia and blackeyed susans (Rudbeckia fulgida ‘Goldsturm’) are still providing colour as the ornamental grasses begin to flower.

Ligularia & rudbeckia-Festival Theatre Garden
Of the garden’s hard structure, Thom Payne said:  “We wanted a great stone wall with greenery growing on it.  The concept is quite mathematical. It’s a cribbage – a series of limestone terraces – that fall away on a grid toward the lowest point.”  Typical of Mr. Payne’s tendency to use the landscape to hint at what can be found indoors, the main path travels through the garden and over the bridge above the formal lily pond – all on the axis of Aisle 2 Entrance Lobby.  “It plays a prominent role in delivering people to the front door.”

Festival Theatre Garden walkway

In creating the cribbing for the terraces, Payne was mindful of his budget but still wanted the natural appearance of stone.  He used pigmented, specially-finished, architectural concrete as an inexpensive foundation for the walls.  He then capped it with 6-inch split-faced Eramosa limestone from local quarries.  “There are a lot of things,” he says, “that are extremely cost-effective, yet I think the overall effect is one of richness, theatricality and permanence.”  Below is a sturdy, gold yarrow (Achillea filipendulina) with a deep red swamp hibiscus.

Yarrow-Achillea filipendulina-Festival Theatre

When it came time to plan the 32 terrace beds, Neil Turnbull drew on a long career as one of the country’s most inspired plantsmen and landscape designers.  In seeking a theme, he hit upon another powerful symbol of early Shakespeare theatre, its festival banners and ribbons.  “I decided to create three ribbons of thyme that flow like curving rivers through the beds,” he explained. (The thyme is evident in the magazine cover above but I suspect other perennials have overwhelmed it somewhat over the years.)  Below is Japanese anemone with blue leadwort (Ceratostigma plumbaginoides).

Anemone x hybrida & Ceratostigma plumbaginoides-Festival Theatre Garden

Known for solving geometry on the drafting table but aesthetics on-site, Turnbull reasoned that the garden’s strength would be in the sheer massiveness of its plantings.  He had 21,000 plants expressly grown, and then placed them in recurring combinations throughout the beds.  In late summer, some of our wonderful natives provide spectacular colour, like goldenrod (Solidago sp.) and magenta-purple New England aster (Symphyotrichum novae-angliae) below.

New England asters-&-goldenrod-Festival Theatre Garden

Lots of fall asters have been used at the theatre, like ‘Andenken an Alma Pötschke’, below, with a honey bee nectaring….

Symphyotrichum novae-angliae 'Alma Potschke'

…. and a dwarf lavender-purple aster paired with ‘Rosy Jane’ gaura (Oenothera lindheimerii), below.

Gaura & asters-Festival Theatre Garden

This summer has seen an extraordinary amount of rain and below-average temperatures until September, when we had a heat wave. So some plants had already begun to undergo a foliage change, like spring-flowering Euphorbia griffithi ‘Fireglow’, below.

As visitors reach the top of the planting beds on their way into the theatre, they cross a bridge over a formal rectangular pool…

As I left the garden, I noted all kind of pollinators flitting about. I saw bumble bees foraging deep in the yellow wax bells (Kirengeshoma palmata)…..

….a carpenter bee nectar-robbing on obedient plant (Physostegia virginiana)….

….and a hover-fly getting lost in the throat of a morning glory (Ipomoea tricolor).

Almost twenty years after my first visit, it was good to see the garden still looking gorgeous and being enjoyed by thousands of theatre-goers annually — plus untold numbers of tiny buzzing and fluttering visitors, too.

The Festival Theatre gardens are located at 55 Queen Street, Stratford, Ontario.  The Festival is open from mid-April to the end of October; for more information visit the Stratford Festival website.

Winter Bark & Bough: A Valentine to Trees

In my part of the world, winter often seems like a time that nature has forgotten. Frozen earth, dirty snow, leafless tree boughs except for the evergreens – a subdued landscape of grey, brown and white. Yet there is life teeming deep in the soil under that snow and spring beckons just months away.  And there is majesty in the skeletal architecture of trees. While returning to Toronto from our cottage on Lake Muskoka one late afternoon recently (and, I hasten to add, I was in the passenger seat), I clicked my camera at tree vignettes flanking Highway 400, the major north-south route linking the city to cottage country and beyond. Forest, farm field, windbreak, granite outcrop… all stood out in moody relief against the January sky.  Photographing at 70 miles an hour doesn’t give sharp results, but as a low-resolution mosaic, it’s a beautiful way to appreciate the winter landscape and the skeletons of trees.

Winter Tree skeletons-Highway 400-Ontario

With winter hanging on for five months or more in Toronto, the architecture of trees becomes an important consideration in garden design. Since I’m a bit of a tree geek, I pay attention to those things, and thought some of my blog readers might share my enjoyment. So here is a roster of hardy shrubs and trees with distinctive winter bark and branching, arranged by botanical name. It’s…um….quite comprehensive — let’s just call it an “encyclotreedia”. Or, given the date, perhaps we can call it a Valentine to Trees. And please note, this is not a recommendation list, merely a photo guide to many dediduous species, native and non-native, well-behaved or potentially invasive. Almost all were photographed in Toronto’s Mount Pleasant Cemetery, the 200-acre arboretum I am so very fortunate to have less than a mile-and-a-half from my home, a place in which I’ve been photographing flora for 20 years.

Acer davidii – Pere David’s Maple: This maple represents one of the hardiest of the beautiful snakebark maples. Its bark is olive-green with silvery vertical stripes intercut with small horizontal, green lenticels. In time, the bark changes to striped light-brown. A beautiful, small, multi-stemmed tree that grows to 30-40 feet (9-12 metres) or so and colours nicely in autumn. Sadly, the one I know has developed sun scald on its exposed flank, but seems to hang on despite the gaping splits in the trunk.

Acer davidii-Pere David's maple-winter trunk

Acer griseum – Paperbark Maple:  I grow this lovely, small, Asian maple in my own garden, regrettably out of my sight line in a side-yard where I cannot appreciate the gorgeous exfoliating bark on its slender red trunk, especially in winter against the snow.  Paperbark maple matures somewhere between 20-30 feet (6-9 metres) with a lovely, vase-shaped form.  Trifoliate leaves turn scarlet in fall.

Acer griseum-Paperbark maple-winter-bark

Acer pseudoplatanus – Sycamore Maple: The Latin name of this large (75-90 feet, 23-27 metre), short-trunked Eurasian maple means “false plane tree”, and its leaves and exfoliating grey-brown bark do bear some resemblance to the American sycamore and Oriental plane tree of the genus Platanus. But like all maples, sycamore maple has opposite branching, unlike alternate-branched plane trees, and its fruit is a samara rather than the spherical “buttonball” fruit of plane trees.  The confusion is heightened by the common name “sycamore”, applied to both the maple and American plane tree or sycamore which derives from the Greek word “sykomoros”, meaning fig-mulberry. But it is thought to refer to a large Middle Eastern fig called Ficus sycamorus, an ancient tree mentioned in the bible; thus the word later became generic for “shade tree”.

Acer pseudoplatanus-Sycamore maple-winter bark

Acer rubrum – Red Maple:  This native tree starts out with smooth, light-grey bark, as with the wonderful fall-colouring Acer rubrum ‘Morgan’, below…..

Acer rubrum 'Morgan'-red maple-young bark

….. before developing its rough, scaly, dark bark later in life, when it can be as tall as 90 feet (27 metres) in wide-open areas, but likely already nearing the end of a life that averages 80 to 100 years.

Acer rubrum-red maple-bark-winter

Acer saccharinum – Silver Maple: We once had a tall, majestic silver maple on the boulevard in front of our house in Toronto, and I counted the rings when the city came to cut it down in 1996.  There were 81, which meant it had been planted when our house was built, around 1915. Its bark and bearing at that age looked like the silver maple below: long, narrow strips of medium grey, many fallen off, and the main trunk dividing into sub-trunks before flaring into elegant limbs on high.  I still miss it.

Acer saccharinum-silver maple-winter-bark

The upper bark of the silver maple is produced in sheet-like plates, something like the bark that the hairy woodpecker is attacking in my video made in Mount Pleasant Cemetery, below.

Acer saccharum – Sugar Maple:  Who hasn’t stood under a sugar maple in autumn and gazed in awe at the sunset array of fall colours, below?  It’s in winter when we notice the dark, furrowed, sometimes curling bark of the trunk leading up to the widespread crown, the massive canopy often missing brittle limbs in old age.  And, of course, just below that furrowed bark is the xylem tissue that scarcely waits until winter’s last gasp before drawing up sweet sap from the thawing soil – sap that turns into delicious maple syrup in the right hands.

Acer saccharum-sugar maple-winter-bark

Sugar maple is the quintessential fall-colouring tree in eastern North America.

Acer saccharum-Sugar maple-fall colour

Aesculus flava – Yellow Buckeye:  When young, yellow buckeye’s bark looks smooth and grey, like beech bark.  As the tree ages to its mature 50-70 feet (15-21 metre) height, its bark develops scales and loose plates.  The tree below developed sub-trunks a short distance from the base.

Aesculus flava-yellow buckeye-winter-bark-trunk

Aesculus hippocastanum – Horsechestnut:  There isn’t much remarkable in the scaly, ridged bark of a mature horsechestnut trunk. What is spectacular is the oval crown and the branches that hang down from 100 feet (30 metres) or so, as if anticipating the weight of those big, beautiful, white flower panicles in June……

Aesculus hippocatanum-horse chestnut-winter

….. and, of course, the plump, sticky, terminal winter buds that look like they were shellacked, and can scarcely wait to burst open on the first warm days of spring.

Aesculus-hippocastanum-horse chestnut-winter bud

Ailanthus altissima – Tree of heaven:  This Chinese tree is such a successful weedy invader throughout North America, where it was once grown as a street tree,  its clones, suckers and self-seeded saplings pop up in cracks in the pavement and untended lots everywhere. It is more likely to be described as “tree of hell” than its normal common name.  Fast-growing, it matures at 60-80 feet (18-24 metres), its bark green and smooth on young trees, but grey with rough furrows on older trees.  Tree of heaven gained notoriety in 1943 when it was featured as the central metaphor in the Betty Smith novel A Tree Grows in Brooklyn.

Ailanthus altissima-tree of heaven-winter bark-trunk

Alnus incana – European grey alder: Look up from the smooth, lenticel-engraved bark of grey alder in winter, and you’ll see the remnants of last summer: the little black, seed-bearing, female cones. Grey alder grows naturally in damp soil, but is also tolerant of dry soil. It can reach 50 feet (15 metres).

Alnus-incana-grey alder-winter bark

Betula alleghaniensis – Yellow birch: If you see yellow birch in winter with its shiny, peeling bark and horizontal lenticels , you’re forgiven for thinking you’ve stumbled upon a beautiful cherry. For that’s what a young yellow birch resembles.  It grows to 75 feet (23 metres) in ideal conditions.

Betula alleghaniensis-yellow birch-trunk-bark-winter

Betula ermanii – Erman’s birch: Though quite variable in appearance, Erman’s birch or Russian rock birch can have creamy-white bark like paper birch or resemble native river birch, in that older trees develop peeling, shredded bark in brown, gray, orange and white. Often multi-stemmed, Erman’s birch matures at around 60 feet (18 metres).

Betula ermanii-Erman's birch-bark-trunk-winter

Betula lenta – Cherry birch, Sweet birch:  I love this native birch, which should be grown much more than it is. The wood is used for furniture and flooring. The bark starts as a reddish-brown, turns dark gray, then develops thin scales as it ages. It grows to 50-60 feet (15-18 metres) in favorable conditions.

Betula lenta-cherry birch-winter bark

In autumn, cherry birch with its apricot orange leaves is an exquisite part of the fall color parade.

Betula lenta-Cherry birch-autumn color

Betula nigra – River birch:  As the name suggests, this is a tree for damp places, but not small places. When happy, it can reach 70 feet (21 metres), often multi-stemmed, its bark flaked with a patchwork of cream, buff, apricot and brown papery scales.

Betula nigra-river birch-winter-bark

Betula papyrifera – Paper birch: Don’t we all have a special place in our hearts for the paper birch? Even with its insect enemies – the bronze birch borer, birch leafminer – don’t we all think romantically of Robert Frost’s Birches? That shimmering white bark, the black hawk-eyes winking from the trunk, the leaves fluttering like tiny golden flags in autumn.

Betula papyrifera-paper birch-winter-bark-trunk

Paper birch grows to 70 feet (21 metres), often multi-stemmed; its brown park with pale lenticels eventually turns white.  Indeed, as Robert Frost once wrote, one could do much worse than be a swinger of birches, like the ones shown growing with hemlocks on the road behind my Lake Muskoka cottage.

Betula-papyrifera-birches-winter-Robert Frost

Betula utilis var. jacquemontii – White-barked Himalayan birch: Many experts consider this to be a finer landscape alternative than our native paper birch. Selected forms have shimmering-white bark on a slender, often multi-stemmed tree that reaches 30-40 feet (9-12 metres). Sadly, it is also susceptible in time to the bronze birch borer.

Betula jacquemontii-Himalayan birch-winter bark

Carpinus caroliniana – Blue beech, American hornbeam: This lovely little understory tree is at least as wide as it is tall (20-30 feet, 6-9 metres), with muscled grey bark (another of its common names is ‘musclewood’) and a fluted trunk. It’s one of my favourite northeastern natives, with delicate, birch-like leaves that turn orange in fall.

Carpinus caroliniana-Blue Beech-Winter-Bark

Carya cordiformis – Bitternut hickory:  When young, this tree’s bark is smooth and grey; as it matures to a height of 100 feet (30 metres) or more, the bark develops wavy ridges and regular vertical furrows.  Bitternut hickory lives about 200 years and its durable wood is used for furniture.

Carya cordiformis-bitternut hickory-winter-bark

Carya ovata – Shagbark hickory:  One of my favourite trunks to photograph, so illustrative of its common name. As a young tree, this hickory’s bark is grey and smooth; as it matures to over 120 feet (36 metres) in height   metres), the bark breaks into long, vertical plates which adhere to the bole in the middle while the ends curve away and produce the ‘shaggy’ look.  It is long-lived, to 300 years or more and produces edible nuts.

Carya ovata-shagbark hickory-winter bark

Castanea dentata – American chestnut:  There are precious few of these iconic trees left in North America, but Mount Pleasant Cemetery has a number of small specimens, their sawn upper limbs a clue to the introduced chestnut blight that decimated the North American population in the early 20th century.  A Carolinian species native to the northern shore of Lake Erie, it once grew to lofty heights of over 100 feet (30 metres), but is now seen in the wild as small sprout trees from dead stumps. The trunk on the smallish tree below with its interlaced furrows and ridges indicates its old age; young bark is smooth and chestnut-brown.

Castanea dentata-American chestnut-winter bark

Castanea mollissima – Chinese chestnut: A small-medium sized tree growing to about 40 feet (12 metres) with an open canopy and wide-spreading branches, Chinese chestnut is resistant to the chestnut blight that kills American chestnut. Like the tree below with its brown, ridged bark, foliage is marcescent, with leaves often persisting on the tree throughout winter. It produces edible nuts (though not the delicacies of the sweet Spanish chestnut) and is currently the subject of experiments to produce a viable hybrid with the American chestnut.

Castanea mollissima-Chinese chetnut-winter-bark

Catalpa speciosa – Northern catalpa:  Of all the sylva of the American forest, Northern catalpa is the most tropical in appearance, with purple-splotched white flowers held in big panicles.. Though native to a relatively small swath from Kansas south to Texas and east to Louisiana, it is a remarkably hardy tree and thrives in Toronto (USDA Zone 5, like Chicago). It’s bark is grey-brown with shallow fissures and its crown is irregular with masses of crooked branches that give it a witchy appearance. However, certain trees, interestingly, develop a tall, narrower profile than the one below.

Catalpa speciosa-northern catalpa-winter

Celtis occidentalis – Hackberry: This is one of those nondescript, native trees (to 60 feet – 18 metres) that nonetheless proves its worth as a pollution-tolerant choice for city streets. Its bark is smooth and greyish when young, but as it matures it develops corky wart-like bumps that form wavy, vertical ridges.

Celtis occidentalis-hackberry-bark-winter

Cercidiphyllum japonicum – Katsura: This most elegant of Asian trees has bark that starts out smooth, but later splits into thin, papery strips as it grows (often multi-stemmed) to a height of 30-40 feet (9-12 metres) or more.  Its senescing, heart-shaped leaves produce maltose, which in the right conditions produces a burnt sugar aroma as one walks near them in autumn.

Cercidiphyllum japonicum-katsura-bark-winter

Katsura is a dioecious species, meaning there are male and female trees. In winter, the remnants of last summer’s fruit pods often decorate the canopy of a female katsura tree.

Cercidiphyllum japonicum-Katsura-female-capsules-winter

Cladrastis kentukea – Yellowwood : This is a favourite tree of mine when it deigns to flower in late spring or early summer with masses of pendulous, wisteria-like, white flower clusters (below) – an auspicious event that happens once every 3 or 4 years, if you’re lucky! It’s native to the southern U.S. but hardy here in Toronto, though subject to sunscald in winter.  Bark is smooth, grey and beech-like on a small-medium tree reaching 30-50 feet (10-15 metres).

Cladrastis kentukea-Yellowwood-winter-bark

The spectacular, cascading flowers of the yellowwood aren’t produced every year, but they are a beautiful sight when they are, as here in Toronto’s Mount Pleasant Cemetery.

Cladrastis kentukea-Yellowwood-flowers

Cornus mas – Cornelian cherry:  One of my favourite shrubs or small trees, quite likely because its bright-yellow umbel flowers are among the very first to bloom in late winter or early spring. This dogwood, native to Europe and western Asia,  reaches 20 feet (9 metres) tall and almost as wide, and has the prettiest mottled tan-and-cream bark on its slender trunk(s).

Cornus mas-Cornelian cherry-winter-bark

Cornus sanguinea – Common European dogwood – There are shrubs, of course, that boast brilliant winter bark, and none is more beautiful than the selections of European dogwood that celebrate the cold ‘midwinter’. This is ‘Midwinter Beauty’, below, but ‘Midwinter Fire’ is just as brilliant, with blazing sunset colours against a snowy landscape.  Be sure to cut back your Cornus sanguinea in early spring in order to guarantee bright stem colour from the new growth in the following winter.

Cornus sanguinea-'Winter Beauty'-dogwood

Cornus sericea – Red-osier dogwood: Though it might be common and a little old hat by now, the red canes of the new growth of ultra-hardy red-osier dogwood are always luminous in the winter garden. But do remember that you need to cut back the older canes in late winter or early spring, in order to encourage the bright-red colour of the new ones for the following winter.

Cornus sericea-red winter stems

Cornus sericea ‘Flavamirea’ – Yellow-twig dogwood: I love the golden canes of yellow-twig dogwood in winter; they add a little pool of sunlight to an otherwise barren spot. Left unpruned, this dogwood can reach 8 feet (2.4 metres), but as with red-osier dogwood, its brilliant colour is produced on new growth, so an annual cutting-back in late winter or early spring is necessary to ensure a good show.

Cornus sericea 'Flavamirea'-gold winter stems

And in case you’re wondering what to plant beneath those lovely golden stems, how about a sea of blue-flowered Siberian squill (Scilla siberica)?

Cornus sericea 'Flavamirea' & Scilla siberica

Corylus colurna – Turkish filbert or hazel:  A refined, pyramidal shape, relatively small stature (around 45 feet or 14 metres tall in colder regions) and problem-free demeanor often result in this tree being recommended for use in small gardens. It produces small, edible, but non-commercial nuts; however, its hardiness makes it a good rootstock for orchard species of filbert and hazel. In winter, below, the light brown, corky, flaking trunk and bark are quite attractive.

Corylus colurna-Turkish filbert-winter-bark

Fagus grandifolia – American beech:  This beloved, stately native of our northeast forests is under attack from beech bark fungal disease, which is vectored by an introduced European scale insect feeding on sap and ultimately leads to formation of a canker that causes severe die-back.  I cannot imagine what the deep woods behind our cottage on Lake Muskoka would look like without the muscled, grey bark and stout trunk of the American beech, below.

Fagus grandifolia-American beech-winter-bark

Fagus sylvatica – European beech: – A beautiful tree with a commanding presence, up to 90 feet (27 metres) tall,  and many cultivars that feature pyramidal or weeping shape and colourful leaves.  Sadly, the same beech bark disease (BBD) as occurs on native beeches is also claiming mature European beeches, like the magnificent copper beech (Fagus sylvatica ‘Cuprea’) shown below.

Fagus sylvatica 'Cuprea'-copper beech-winter-bark

Fraxinus pensylvanica – Green ash:  If there are any healthy native ashes left standing in North America after the reign of terror of the emerald ash borer, their trunks will look something like the one below, with its grey, ridged, corky bark. (Speaking personally, we lost our ash to EAB a few years ago, and most other ashes in Toronto will be removed in time.)

Fraxinus pensylvanica-green ash-winter bark-trunk

Ginkgo biloba – Maidenhair tree: As distinctive as the fan-shaped leaves of this stately deciduous conifer are – and luscious yellow in autumn – the brown bark is also attractive, with deep furrows and raised ridges. In winter, you can look up into the crown of a ginkgo and see the short spurs bearing the axial winter buds lining the bare branches.

Ginkgo biloba-maidenhair tree-winter-bark-spurs

Gleditsia triacanthos var. inermis – Thornless Honey locust: I am told that if you look carefully at the branching of a thornless honey locust, you’ll see a distinctive zigzag pattern to the growth of the twigs. The bark on young trees is a smooth olive-brown; as the tree ages, it becomes grey, fissured and flaky, often revealing the red under-bark. This form has a lack of vicious thorns, which distinguishes it from the main species. The elegant canopy created by the fine-textured foliage of honey locust has resulted in it being selected for cultivars like ‘Shademaster’, ‘Moraine’ and ‘Sunburst’. Sadly, honey locusts are subject to disease and insect pests.  And despite being called “honey locust”, they’re not much visited by bees; the name actually derived from the sweet pulp within the seedpods.

Gleditsia triacanthos-var. inermis-thornless honey locust-winter

Gymnocladus dioicus – Kentucky coffeetree – The Latin name Gymnocladus means “naked branch”, and describes the tree’s propensity for leafing out late and dropping its leaves early in autumn, thus leaving naked branches for most of the year. “Dioicus” describes its reproductive strategy, dioecy, meaning male and female flowers are borne on separate trees. On the ‘species at risk’ list in Ontario, Kentucky coffeetree once grew abundantly in southwest Ontario at the northern limit of its native range. But trees in Toronto do very well, and male trees (more desirable because of the huge, rattling seedpods of female trees) are available in the city’s Urban Forestry boulevard tree-planting program. The scaly bark is grey-brown and fissured on trees that reach 50-80 feet (24 metres) at maturity.

Gymnocladus dioicus-Kentucky coffeetree-winter bark-trunk

Those lush Kentucky coffeetree leaves, incidentally, are doubly compound or ‘bipinnately compound’ – and the largest leaves of any deciduous North American tree.  Their intricacy makes the canopy spectacularly beautiful in summer, below.

Gymnocladus dioicus-Kentucky coffeetree-bipinnate foliage

Juglans cinerea – Butternut: We once had a tall butternut tree in the back of our garden. It produced ridged, oval, sticky green fruits that the squirrels ate, leaving husks all over the lawn (like black walnut, below).  My husband loved a particular curved branch that extended across our garden, and I loved its history as a dye plant for the brown uniforms of the Confederate Army (the soldiers were nicknamed “butternuts”). Sadly, in the 1990s, it developed the butternut canker that would ultimately kill it – and has caused its population to decline throughout North America. I’m delighted that the tree below still survives in Mount Pleasant Cemetery, its trunk layered with grey-brown, diamond-ridged bark.

Juglans cinerea-Butternut-bark-trunk-winter

Juglans nigra – Black walnut: I live right under a huge black walnut, below – or perhaps I should call it a raccoon home…..Though the big green walnuts drive me crazy in the fall as they rain down on my roof like billiard balls, and the tree frightens me on a night like the one earlier this week, when an ice storm coated all the limbs, I do adore its graceful canopy and the cardinals that sing in its branches just above my bedroom ceiling.  But my next-door neighbour and I have spent a fortune on arborists over the decades to cable its limbs and restrain its exuberance, while still providing lots of growth points.

Juglans nigra-Black walnut-over house

Black walnut has a sturdy trunk with bark that’s braided with diamond-patterned furrows. From the time the United States was colonized in the early 1600s, black walnut wood was recognized as superior, and used for cabinet-making and gunstocks. The tree can reach 100 feet (30 metres) in moist, deep soil, and ensures its place in the natural forest by secreting juglone from its roots, bark, shoots and leaves. The botanical name for this is allelopathy, but many natural understory shade plants are unaffected by juglone.

Juglans-nigra-Black walnut-winter-bark

And… because I’m not really happy with my winter photos of black walnut, here’s a summer shot illustrating that elegant canopy. Isn’t this spectacular?

Juglans nigra-black walnut-summer canopy

Larix kaempferi – Japanese larch: The larches, like dawn redwood and bald cypress, are deciduous conifers that shed their needle-like leaves in autumn.  They perform well in damp soil (the one below is growing in the run-off of a water feature) and turn yellow in autumn. Japanese larch can grow to 80 feet at maturity, its trunk reaching 3-4 feet (90-120 cm) in diameter. A young tree like this one still has its smooth grey-brown bark; in time, it will form plate-like strips that peel off to reveal the red underbark.

Larix kaempferi-Japanese larch-winter

Larix laricina – Eastern tamarack: Though it prefers the cool, wet ground of sphagnum bogs or muskeg in the north country (it grows the furthest north of any tree in North America), the tamarack can be grown in adequately moist soil in a garden, too.  Reaching 20-35 feet (6-15 metres) in height, it can be recognized by its slender profile, feathery leaves that turn brilliant-gold in autumn and dark cones that remain on the tree for years. Its dark grey-brown bark is thin and scaly.  And, as one observer says: “In winter, it is the deadest-looking vegetation on the globe.”

Larix laricina-eastern tamarack-bark-winter

Liquidambar styraciflua – Sweetgum: Perhaps if I lived in Virginia or North Carolina or Alabama where indigenous sweetgum trees grow in abandoned fields, I might have a more jaded view of this tall, majestic native southerner. But I have long adored the tall sweetgum that towers majestically over the stone angel in Mount Pleasant Cemetery, especially in autumn when the star-shaped leaves take on yellow, amber, scarlet and crimson hues and the “gum balls” dangle from the canopy. (See photo below.) Sweetgum grows 60-75 feet (18-23 metres) tall and 40-55 feet (12-17 metres) wide. Back in the pioneer days, the resinous gum exuded by the tree was used as chewing gum; it was also given to Civil War soldiers to treat dysentery.  Though sweetgum isn’t native to Canada, we certainly saw a lot of gumwood trim used in Toronto houses at one time – including one I owned. If I were young, I would plant a small liquidambar in my garden; in the meantime, I’ll enjoy standing under that sweetgum in the cemetery.

My favourite sweetgum watches over this stone angel in Mount Pleasant Cemetery. This is how it looks in autumn.

Liriodendron tulipifera – Tuliptree, Yellow poplar: The tallest eastern hardwood, tuliptree can grow as high as 160 feet (50 metres) in the rich forests of the Southern Piedmont in Virginia and Georgia. In its stands in Norfolk County in southern Ontario near Lake Erie, at the northern limit of its native range, it tends to reach a more modest height at maturity. Its bark is furrowed and brown with intersecting ridges. In the wild its trunk can remain limbless for up to 50 feet (15 metres) before branching out. Below is the winter bark of a lovely variegated cultivar called ‘Majestic Beauty’.

Liriodendron tulipifera 'Majestic Beauty'-variegated tuliptree-winter-trunk

Liriodendron flowers are exquisite, like yellow chalices (i.e. tulips) flamed with orange, and very attractive to bees. (In fact, the main nectar flow for an Atlanta beekeeper I’ve interviewed is April, when it flowers in the Georgia forests.)

Liriodendron tulipifera-flower

Malus ‘Dolgo’ – Crabapple:  Crabapples aren’t known for their attractive bark, but the “patchwork quilt” effect on the trunk of many crabs is often enough to aid in their identification in winter.  This is old-fashioned ‘Dolgo’; its large fruit make it one of the best selections for crabapple jelly.

Malus 'Dolgo'-crab apple-winter-bark-trunk

Malus tschonoskii – Pillar apple, Chonosuki crab: Here’s an unusual small tree, native to Japan, quite rare in cultivation and one that is often mistaken for a cherry in winter, because of its prunus-like bark.  (In fact, pillar apple was once considered to be a pear, and placed in the Pyrus genus.)  Narrowly upright to around 30 feet (9 metres), it  puts on a beautiful show in autumn, when the multi-colored red, orange and gold foliage is arrayed against the tree’s smooth, grey limbs.

Malus tschonoskii-Pillar apple-winter-bark

Metasequoia glyptostroboides – Dawn redwood: An iconic “fossil tree”, once thought extinct, until a remarkable series of events featuring its modern discovery in the 1940s in the mountains of Hubei, China, and the detective work of Chinese botanists who were able to connect it to an ancient fossil studied by a Japanese paleobotanist a few years earlier. Though I decided to focus this winter bark blog on deciduous trees, who cannot appreciate the amazing, fibrous, peeling, red-and-brown bark and perfect, conical form of the dawn redwood?  And since, like the gingko, it’s a ‘deciduous conifer’, it met half the criteria in any case. Dawn redwood can reach at least 100 feet (30 metres) in perfect conditions, which in China include shady, moist sites near water, especially ravines and creek banks.

Metasequoia glyptostroboides-dawn redwood-winter-bark-trunk

Morus rubra – Red mulberry:  This Eastern North America native with its brown, furrowed bark and spreading crown is often confused with the Asian white mulberry (M. alba), which was imported from China to create a silk-spinning industry and later became an invasive in many regions. Although Donald Culross Peattie wrote that Choctaw women made a shawl from red mulberry inner bark, the native tree did not find favour with silkworms. But red mulberry’s blackberry-like fruit does find favour with birds and small animals, not to mention foragers who use it in jams, pies and cordials.

Morus rubra-red mulberry-winter-bark-trunk

Ostrya virginiana – Eastern ironwood, American hophornbeam:   Donald Culross Peattie writes of this small, native, understory tree in his wonderful A Natural History of Trees of Central and Eastern North America:  In our rich sylva, a little tree like the Ironwood melts into the summer greenery, or the silver intricacy of naked twigs in the winter months, in a way that makes it difficult to pick out and identify……. Everything about this little tree is at once serviceable and self-effacing.  Such members of any society are easily overlooked, but well worth knowing.” In the winter, it’s the bark of the trunk that’s most noticeable: greyish brown, with fine, flaked scales, covering wood that is the second hardest (after Cornus florida) of all native trees. In the canopy, like little damselflies suspended from the branches, are the old catkins, flying alongside the odd old leaf, dainty reminders of the summer past.

Ostrya virginiana-Ironwood-hophornbeam-winter-bark-trunk

Parrotia persica – Persian ironwood:  There is one, lonely Persian parrotia in Mount Pleasant Cemetery, and it is a sweet little thing. A witch hazel relative native to Iran and the Caucasus, it has leathery leaves that turn myriad shades of gold, orange and crimson in autumn – but not in a fireworks way (in Toronto at least), more ‘a few here and a few there’. Growing to 40 feet (12 metres) with a dense, spreading crown, it features attractive, smooth, mottled bark, but branching starts so low on the tree, it’s a challenge to make a good photo of the trunk.

Parrotia-persica-Persian-ir

Phellodendron amurense – Amur cork tree: I am very fond of this small Asian tree (30-45 feet, 9-14 metres). It bears lovely compound foliage that turns a soft-yellow in autumn, clusters of deep-blue fruit (beloved by robins) and interesting, ridged, corky bark. It’s most happy in moist, rich soil, but will tolerate some drought. Dioecious, the female trees have proven invasive in certain warmer regions in North America.

Phellodendron amurense-Amur cork tree-winter-bark-trunk

Platanus x acerifolia – London plane tree: There is no mistaking this handsome tree, a hybrid of the Oriental plane tree (P. orientalis) and the American sycamore (P. occidentalis). Its smooth, mottled cream-olive-brown exfoliating bark graces a stocky trunk and branches on a tree that can reach 80 feet (24 metres) in height and almost as much in spread. Much more pollution-tolerant than its American parent (below), London plane trees grace city avenues throughout the temperate world.

Platanus x acerifolia-London plane-winter

Here’s a closeup of the gorgeous mottled bark of London plane tree.

Platanus x acerifolia bark-London plane-close-up

Platanus occidentalis – American sycamore:  This beloved native American tree, one of the parents of London plane tree, above, grows in a few spots in Mount Pleasant Cemetery, at the northern limit of its hardiness. On older trees, the trunk loses its mottled appearance and develops tight, geometric scales, but the limbs still show the exfoliating, leopardskin colouration. Sycamores – the largest deciduous trees in North America –  are the stuff of legend in the eastern United States, especially in the bottomlands of the Ohio Valley, where they once grew to heights of 160 feet (49 metres) with trunks 13 feet (4 metres) in diameter. Their distinctive, hanging ‘buttonball” fruit is a tight, spherical aggregation of achenes – seeds fixed with little bit of fluff to aid them on the wind.

Platanus occidentalis-American sycamore-winter bark-trunk

Populus alba – White poplar: Native to Europe, Asia and North Africa, this large poplar was introduced into North America in 1748 and has been so successful at propagating itself that it is now on the pernicious weed list of many regions. It grows 50-75 feet tall (15-23 metres) or more. The big trunk on old trees is dark-grey, but the upper branches are snow-white and very beautiful, especially with the silvery backs of the blue-green, maple-like, summer leaves fluttering in the wind.

Populus alba-White poplar-winter bark

Prunus maackii – Amur cherry:  I love this rugged little cherry with its lustrous, curling, coppery-brown bark on young trees. Native to Manchuria and southeadt Russia, it was discovered by Russian naturalist Richard Maak in 1855 on the banks of the Amur River. Its extreme hardiness (USDA Zone 3) destined it for use as a street tree in prairie cities. It normally reaches 15-25 feet (4.6-6 metres) in height and width, but can grow taller in ideal conditions – which means the moist soil of the summer monsoon region of China.

Here is Amur cherry in May when the white chokecherry flower clusters are in bloom, below. This is in a small courtyard at Toronto Botanical Garden, where they have cleverly underplanted it with bugleweed (Ajuga).

Prunus maackii-Amur cherry-flowers

Prunus serrula – Tibetan cherry, also called birchbark and paperbark cherry, makes quite a splash with its shiny, coppery-red trunk on a small tree that reaches 20-30 feet (6 -8 metres). Its foliage is narrow and willow-like, and it bars down-facing clusters of unremarkable, single, white flowers in early spring.  Strangely, although it’s purported to be hardy to USDA Zone 5, I’ve never seen it in the east, either in Canada or the U.S. (though there’s supposed to be on in the Rock Garden at New York Botanical Garden).

Prunus serrulata – Japanese cherry: Perhaps no other bark is as well-known and beloved as the shiny, smooth, lenticel-etched bark of the myriad Japanese cherry trees. This is because the trees (called sakura in Japan) are part of an annual Japanese spring tradition called hanami, or cherry blossom festival. Below is the bark of ‘Shogetsu’, a late-blooming, pale pink, double-flowered Japanese cherry.

Prunus serrulata 'Shogetsu'-Japanese cherry-winter bark-trunk

Pterocarya fraxinifolia – Caucasian wingnut: I’ve only seen this broad, majestic, walnut relative in Mount Pleasant Cemetery, where it dangles its 12-inch (30 cm) green fruit chains like long, emerald earrings from amongst the lush, pinnate foliage.  Native to Iran and Central Asia, Caucasian wingnut is fast-growing to 80 feet (24 metres) tall with a 60 foot (16 metres) spread.  Often multi-trunked, the bark is grey-brown, with long, ridged furrows. As in the photo below, the low branching and massive weight of the limbs often necessitates cabling.

Pterocarya fraxinifolia-Caucasian wingnut-winter bark

Here are those amazing green fruits of the Caucasian wingnut.

Pterocarya-fraxinifolia-fru

Quercus alba – Eastern white oak: At maturity, the white oak wears the word ‘majestic’ naturally. Maturing at 60-100 feet with a spread up to 50 feet (15 metres), its stocky trunk with scaly, grey bark often peeling in plates and patches, last year’s leaves hanging on in places to ……

Quercus alba-white oak-winter-canopy-bark

…. its massive canopy and large limbs – all describe the tree many naturalists revere as the best in the forest. Listen to Donald Culross Peattie, from his wonderful A Natural History of Trees of Central and Eastern North America:  If Oak is the king of trees, as tradition has it, then the White Oak, throughout its range, is the king of kings…no other tree in our sylva has so great a spread. The mighty branches themselves, often fifty feet long or more, leave the trunk nearly at right angles and extend their arms benignantly above the generations of men who pass beneath them.  Indeed, the fortunate possessor of an old White Oak, owns a sort of second home, an outdoor mansion of shade, and greenery, and leafy music.”   Here is an autumn image of an “outdoor mansion” built of white oak.

Quercus alba-White oak-autumn color

Quercus macrocarpa – Bur oak: Not particularly well-known, even in southern Ontario where it is the most common native oak, this eastern North American tree defines “adaptable”. It likes cold winters and hot summers and tolerates a variety of soil types and moisture (though it is generally found on flood plains). Rugged and handsome with ridged, grey bark on a tree that reaches 50 to 100 feet (15-30 metres), depending on conditions, it is a pollution-tolerant choice for those who want a sturdy, wildlife-friendly native oak.

Quercus macrocarpa-bur oak-winter bark

Quercus palustris – Pin oak: Native to the Carolinian zone near Lake Erie, pin oak prefers moist places (“palustris” means water-loving) but seems to survive in Toronto with normal garden irrigation. It tolerates clay but must have acidic soil; alkaline conditions will cause chlorosis and yellowing of the leaves.  Its neat, pyramidal shape, reasonable height (60 feet – 18 metres) and beautiful fall color recommend it – provided soil pH is considered. This is the dense horizontal branching of a pin oak in winter. Note that the bark is changing its habit from grey-brown and fairly smooth to thinly-ridged and furrowed.

Quercus palustris-pin oak-winter bark-trunk

Here is the spectacular fall colour of pin oaks in Toronto. The orange leaf colour in the tree at left is almost certainly a result of chlorosis from localized alkaline soil.

Quercus palustris-pin oak-fall colour

Quercus rubra – Northern red oak: Perhaps because they grow all around us, along with white pines, on the granite bedrock of Lake Muskoka, I adore Northern red oaks. From their boughs, I hear the cheeky call of the blue jays, the chattering of chickadees, the peeeeep of the foraging downy woodpecker. Their abundant acorns feed squirrels and chipmunks.  They turn glowing amber to deep red in autumn, long after the red and sugar maples have lost their leaves. Up there, the enemy is a dry summer and the odd infestation of army caterpillars. They tend not to grow as tall on granite as red oaks do here in the city, where they can reach 60 to 70 feet (18-21 metres) and a spread of 40 – 60 feet (12-18 metres), with greyish bark ridged with shallow furrows.

Quercus rubra-northern red oak-winter-bark

Quercus Crimson Spire™ – Hybrid Oak: There are several fastigiate oaks for use in smaller spaces, but this tightly columnar hybrid selection (Quercus ‘Crimschmidt’) of English oak (Q. robur) and white oak (Q. alba) is a stunning tree. It grows to 45 feet (14 metres) tall and 15 feet (4.5 metres) wide. As for the winter bark, there are so many marcescent leaves held on to Crimson Spire until spring, it is truthfully somewhat difficult to appreciate the bark without standing right beside the trunk.

Quercus Crimson Spire-oak-'Crimschmidt'-winter-marcescent leaves

Robinia pseudoacacia – Black locust: On a warm, late spring night, sometime around the first week of June in Toronto, an enchanting perfume wafts on the air – a scent that reminds some people of orange blossoms. If you chase it down, or rather “up”, you’ll find it’s coming from the abundant, white flower clusters of a tall tree with pea-like leaves. So sweet are the flowers of black locust that the volatile oil has been used as an absolute in the perfume industry, and the flowers produce a honey so clear, it’s said to look like the glass that holds it. Though indigenous to the central Appalachians, black locust has successfully made its way throughout North America and Europe – partly through commerce, and partly through its highly invasive self-seeding. There is no mistaking the bark of a black locust; it is thick and deeply grooved in a ropy pattern, on a trunk that’s often ramrod straight, as below. Though certain populations of very straight, high-branching black locusts were lent the name ‘shipmast locust’, the heavy, decay-resistant wood was evidently used for ship keels, not for masting, which requires lighter softwoods.

Robinia pseudoacacia-Black locust-winter-trunk

Salix × sepulcralis ‘Chrysocoma’ – Weeping willow:  What can you say about a grand weeping willow?  In late winter or early spring, when the long shoots brighten and the dainty catkins open, it’s as if the tree draped itself with dangling jewelry of the finest gold. Of course, you can also say the wood is brittle and prone to breaking, the fallen shoots make a terrible mess in small gardens, the tree wreaks havoc with underground plumbing and though it’s a rapid grower, it also declines quickly. Weeping willow bark is deeply grooved with patterned ridges.

Salix x sepulcralis 'Chrysocoma'-Golden weeping willow-winter-bark

Sorbus aucuparia ‘Rossica’ – Russian mountain ash:  Another ultra-hardy pyramidal tree for the small garden, this selection of mountain ash bears clusters of white flowers in late spring and bird-friendly orange fruit in autumn as the compound leaves change colour to copper-orange.  It grows around 30 feet (9 metres) tall with an 18 foot (5.5 metre) spread. On young trees, the bark is dark-brownish-grey and shiny with prominent lenticels; as the tree ages, the bark splits and develops cracks and scales. Mountain ash, or rowan as it’s called in Britain, rarely lives more than 80 years, and is susceptible to a number of diseases.

Sorbus aucuparia 'Rossica'-mountain ash-winter bark

Stewartia pseudocamellia – Korean Stewartia: Though they are fine collector plants, there aren’t many stewartias in the Toronto region; they are not reliably hardy and need moist soil and protection from late day sun.  I photographed my little winter specimen in a courtyard at the Toronto Botanical Garden, where it gets morning sun and is sheltered from cold wind. However, it’s tempting to seek out one of the few specialist nurseries that sell stewartia,for its luscious, camellia-like, white, June blossoms, its magnificent autumn leaf colour and this gorgeous mottled cream-and-brown bark.  Korean stewartia grows to 40 feet (12 metres) with a 30 foot (9 metres) spread, beginning to branch outward very close to the ground. 

Stewartia pseudocamellia-winter bark

Tilia cordata – Littleleaf linden:  When the lindens – or, as the English call them, “limes” – flower in early summer, the air is sweet beneath their boughs.  Bees, hover flies and butterflies buzz in the flowers, as befits a genus that produces a monofloral honey. In the United States, basswood (T. americana) and white basswood (T. heterophylla), aka “the bee tree” are the beekeeper’s friends, but in eastern Europe, many tilia species are used for honey production. (See my pollinator array photo below).   Littleleaf linden has been a popular street tree and specimen tree in Toronto, but those who have tried to garden under it rue the gloomy shade from its broad crown. It is densely-branched and reaches 60 feet (18 metres) with a 40 foot (12 metres) spread. Linden bark is grey and shallowly fissured.

Tilia cordata-Littleleaf linden-winter-bark

Pollinators forage on linden flowers, below. Clockwise from top left, metallic green bee, swallowtail butterfly and European honey bee on American basswood (T. americana) flowers; hoverfly on Caucasian lime (T. x euchlora) flowers. Large-scale bumble bee deaths of bees nectaring on Tilia species have been reported in the U.S. and Europe, but such toxicity is not well understood. (I have personally seen bumble bees lying in gardens under flowering lindens).  It is now hypothesized that bumble bees will often expend all their energy foraging on lindens whose nectar is depleted, leading to collapse and death.

Ulmus americana – American elm: It is bittersweet looking up into the winter crown of a mature American elm, for this old tree is a survivor of a plague that decimated the landscape of its kin. When Dutch elm disease was first discovered near port cities in eastern North America in 1930, imported from Europe on elm logs to be milled for veneer, there were an estimated 77 million elms on the continent. Six decades later, that number had been reduced by 75%. Today’s surviving trees stand alone, like this one, its grey bark ridged and fissured, its arching limbs (those that have not fallen to ice storms) giving way to the elegant drooping branchlets that mark its profile as unique.

Ulmus americana-American elm-winter-bark-trunk

Ulmus pumila – Siberian elm – Here is the winter bark of a successful invader, a tree once used for hedging in my neck of the woods, as one might use beech or privet. But Ulmus pumila is no wimpy privet; it ‘hedges’ its bets by waiting until the gardener is not looking, then shoots for the moon. Paradoxically, its specific epithet means ‘dwarf’, but it is anything but small. This tree, for example, with its diamond-furrowed bark and adventitious shoots emerging from cankers on the trunk, is well over 60 feet (18 metres).

Ulmus pumila-Siberian elm-winter-bark-trunk

Zelkova serrata – Japanese zelkova: The stately zelkova is my final winter bark entry, and a worthy one at that. This elm relative has grey-brown, beech-like bark with raised lenticels, exfoliating as the tree ages.     Pollution-tolerant, it is often planted as a fast-growing street tree, especially the cultivar ‘Green Vase’, which features ascending limbs, an upright shape and excellent fall colour. Zelkova reaches 70 feet (21 metres) at maturity with a 50-foot (15 metres) spread.

The Artful Garden

For 19 years, Suzann and Jon Partridge have turned their beautiful country property near Bracebridge, Ontario into an outdoor gallery featuring the garden-inspired art of dozens of talented Ontario artists.

Artful Garden Sign

Welcome to the Artful Garden, with the 2016 show running from July 23rd through August 14th.

Artful Garden-Partridge-Bracebridge

It is a generous gesture from these accomplished and well-known potters, who met in art class at high school in Toronto more than 45 years ago.

Suzann & Jon Partridge

Jon’s pottery is in collections throughout the world.

Partridge-Pottery Sign

Though the show started almost two decades ago, it was 1974 when the young couple moved to what was then a neglected 100-acre Muskoka farm. Their house is modest and typical of the old brick farmhouses that dot Ontario. It’s also visitors’ introduction to the Artful Garden, which I have been photographing through the years. (Note: Some photos below are from my previous visits.)

Suzanne has worked tirelessly developing her gorgeous gardens, which now total more than a dozen areas. They feature sun-loving perennials like blazing star, left (Liatris spicata) and daylilies.
