Silver Lustre in the Garden

A little holiday song, for those who’ve stuck it out through my Twelve Months of Colour blogs in 2016:

Silver belles, silver belles,
It’s Christmas time in the city.

Ding-a-ling?? No, they don’t ring,

My “Silver Belles” just look pretty.

Row 1:‘Pictum’ Japanese painted fern (Athyrium niponicum); ‘King’s Ransom’ Siberian bugloss (Brunnera macrophylla); ‘Miss Wilmott’s Ghost’ giant sea holly (Eryngium giganteum); Agave parryi; Row 2: Hosta ‘Ultramarine‘; ‘Bascour Zilver’ hens-and-chicks (Sempervivum tectorum); ‘Blue Glow’ fescue (Festuca glauca); Heuchera ‘Rave On’; Row 3: ‘Montgomery’ blue spruce (Picea glauca); ‘Silver Carpet’ lamb’s-ear (Stachys byzantina); ‘Blue Star’ juniper (Juniperus squamata); ‘Sapphire Skies’ yucca (Y.rostrata)

Yes, we’re finally in December, and as befits the tinsel month in my year-long celebration of monthly colour themes, I’ve pulled together a treasure box filled with pieces of silver (and some nice blue-greys) for your garden. You should know that I’m a big fan of grey, especially mixed with that little dash of brown that tips it into ‘taupe’. In fact, my house is painted that colour, and my deck and fence are stained a darker shade of stone-grey. It is a beautiful background for all plants.

If you add a little blue-green to silvery-gray, you get a colour we often describe as “glaucous”. That word has travelled a long way since it was first used by the Greeks, including Homer, as glaukos to mean “gleaming, silvery”. In Latin, it  took on the meaning “bluish-green”, and in the 15h century, the Middle English word glauk meant “bluish-green, gray”.  That fits the color of luscious Tuscan kale, below.

brassica-nero-di-toscana-montreal-botanical-garden

So we’ll look at some lovely plants with glaucous foliage as well.

Shrubs & Trees

Let’s begin with a few trees and shrubs.  Weeping willowleaf pear (Pyrus salicifolia ‘Pendula’) is a pretty little (20 ft – 7 m) tree with silvery-grey foliage. Here it is at Victoria’s Horticulture Centre of the Pacific, underplanted with Allium ‘Purple Sensation’.

pyrus-salicifolia-pendula-horticulture-centre-of-the-pacific

Then we have a true willow, dwarf blue Arctic willow (Salix purpurea ‘Nana’). This is a very hardy, useful shrub, standing about 5 feet (1.5 m) tall and wide, that will lend its soft greyish texture to a variety of applications, including as hedging or a filler.

salix-purpurea-nana

As for conifers, there are lots of blue junipers and silver firs, and of course, blue spruces. For a big silvery tree, perhaps none is as stately as the concolor or white fir (Abies concolor ‘Candicans’).

abies-concolor-candicans

If you want a cool blue-grey spruce at garden level, consider Picea pungens ‘Glauca Procumbens’.

picea-pungens-glauca-procumbens

And I love the look of Juniperus conferta ‘Blue Pacific’, especially as it takes on mauve hues in winter, below, along with Sedum rupestre ‘Angelina’.

juniperus-conferta-blue-pacific

Speaking of winter, there’s even a shrub with silvery fruit that persists into winter: Northern bayberry (Myrica pensylvanica).

myrica-pensylvanica-fruit-northern-bayberry

Though we often think of lavender as perennial, it is actually a sub-shrub. English lavender (Lavandula angustifolia) has greyish-blue foliage, and even the commonly available cultivars like ‘Hidcote’ and ‘Munstead’ will provide a good colour contrast, as they do edging this beautiful potager.

louise-kappus-potager-lavender

But if you want a really silvery, hardy lavender, try ‘Silver Mist’, shown below contrasting with a bronze carex.

lavandula-angustifolia-silver-mist

And if you are in a climate where you can grow the more tender Spanish lavender (Lavandula stoechas), there’s a gorgeous silver-leaved cultivar called ‘Anouk’.

lavandula-stoechas-silver-anouk

Perennials

Who hasn’t seen lamb’s-ears in a perennial border? And who hasn’t questioned whether the plant’s name should be a single lamb or a flock? Kidding aside, using hardy lamb’s-ears (Stachys byzantina)  is one of the easiest ways to inject a note of silver into the garden. Here it is with lady’s mantle (Alchemilla mollis) at Burlington, Ontario’s Royal Botanical Gardens …..

Stachys byzantina with Alchemilla mollis

… and fronting a June border at Vancouver’s Van Dusen Botanical Garden.

stachys-byzantina-van-dusen-botanical-garden

I love the way my pal Marnie White intersperses her lamb’s-ears with pink portulaca.

stachys-byzantina-portulaca-marnie-white-garden

Sea holly has a few beautiful silver forms; this is Eryngium giganteum ‘Miss Willmott’s Ghost’ with liatris and switch grass (Panicum virgatum) at the Toronto Botanical Garden.

eryngium-mrs-willmotts-ghost-liatris-panicum

Siberian bugloss (Brunnera macrophylla) has several cultivars with lovely silvery variegation. This is ‘Jack Frost’.

brunnera-macrophylla-jack-frost

Russian sage (Salvia yangii, formerly Perovskia) has fine silver foliage. Here it is with Liatris spicata.

artemisia-silver-king-liatris-spicata

And this is Artemisia ‘Powis Castle’ creating a silvery pool at the edge of a border.

artemisia-powis-castle

In the fern world, luscious Japanese painted fern (Athyrium niponicum var. pictum) is literally ‘painted’ with silver variegation. The stunning cultivar below is ‘Pewter Lace’.

athyrium-niponicum-pewter-lace

Though they don’t come in pure silver, there are many blue-grey hostas to add texture to a shaded or semi-shaded place. At the Toronto Botanical Garden, I love the juxtaposition of Hosta ‘Blue Angel’ with the silvery-blue glass screen behind it.

hosta-blue-angel-toronto-botanical-garden

Here is an assortment of blue-grey hostas.

1 - Ultramarine; 2 – First Frost; 3 – Fragrant Blue; 4 – Earth Angel; 5 – Paradise Joyce; 6 - Halcyon.

With their rainbow foliage colour and myriad leaf markings, heucheras have become a plant breeder’s bonanza in the past few decades. Below are ‘Rave On’ (left) and ‘Silver Scrolls’ (right).

heucheras

Euphorbias also offer delectable silver makings. Though it’s borderline-hardy where I garden in Toronto, I do love Euphorbia characias ‘Tasmanian Tiger’.

euphorbia-characias-tasmanian-tiger

The silvery foliage of Scotch thistle (Onopordum acanthium) can be quite stunning, but careful it doesn’t escape – clip those flowers before they go to seed.

onopordum-acanthium-cotton-thistle

Grasses

Blue-grey grasses abound. Here’s  Festuca glauca ‘Blue Glow’ with berried cotoneaster and silvery Russian sage (Perovskia atriplicifolia) behind.

festuca-glauca-blue-glow

This is ‘Heavy Metal’ switch grass (Panicum virgatum) – one of my favourites.

panicum-virgatum-heavy-metal

Little bluestem is a wonderful native prairie grass, and ‘Prairie Blues’ has a more pronounced silvery-blue hue.

schizachyrium-scoparium-prairie-blues

‘Wind Dancer’ love grass (Eragrostis elliotii)  is hardy only to USDA Zone 6, but I’ve seen it used as an annual grass to lovely effect.

eragrostis-elliottii-wind-dancer

Tender Shrubs, Annuals & Tropicals

Montreal Botanical Garden knows how to create wonderful knots and parterres with silvery plants. This is the tender grass Melinis nerviglumis ‘Savannah’ (ruby grass – USDA Zone 8-10) with Angelonia ‘Serena Purple’.

melinis-nerviglumis-savannah-angelonia-serena-purple-montreal-botanical

…. and this is Cerastium ‘Columnae Silberteppich’ with lantana.

cerastium-columnae-silberteppich

Montreal Botanical’s Herb Garden has also used silvery herbs in formal design schemes over the years. The tapestry-like knot garden below features the sages (Salvia officinalis) ‘Berrgarten’ and variegated ‘Icterina’ in the circle, along with hedge germander (Teucrium chamaedrys) with the pink flowers; clipped lavender and santolina are in the background.

montreal-botanical-salvia-officinalis-berrgarten-icterina

Here’s a closer look at santolina or cotton thistle (Santolina chamacyparissus) in flower. Its ease of shearing makes it a prime candidate for parterres and knots, but it is only hardy to USDA Zone 6.

santolina-chamaecyparissus-lavender-cotton

There are several Mediterranean plants that fit our silvery-blue theme.   A tender perennial (USDA Zone 8) with silver foliage that can be used as a drought-tolerant annual is Greek mountain tea (Sideritis syriaca).

sideritis-syriaca

And Senecio viravira or silver groundsel has textural foliage.

senecio-viravira-silver-groundsel

Isn’t this combination at the Niagara Botanical Gardens beautiful? The big, felted silver leaves of Salvia argentea with Tradescantia spathacea ‘Tricolor’ seem made for each other.

salvia-argentea-tradescantia-spathacea-tricolor-niagara-botanical-garden

Also at Niagara Botanical one summer, I loved this juxtaposition of blue-grey cardoon (Cynara cardunculus) with the cascading silvery Dichondra argentea in the hanging baskets behind.

cynara-cardunculus-dichondra-argentea-niagara-botanical-garden

Speaking of dichondra, here it is at the Toronto Botanical Garden paired with Centaurea gymnocarpa ‘Colchester White’. This, of course, is the work of the TBG’s container wizard Paul Zammit.

dichondra-argentea-centaurea-gymnocarpa-colchester-white-toronto-botanical-garden

Dusty miller (Centaurea cineraria) is an old-fashioned annual that’s easy to source and offers a lovely hit of silver, as with this rich autumn combination of dusty miller and ornamental cabbages.

dusty-miller-senecio-cinerarea

We mustn’t forget the spectacular leaves of the newer Rex begonias like ‘Escargot’, below, many of which have silver markings.

begonia-escargot

There are loads of silvery succulents available, because being silver-grey (reflecting the sun) and being succulent (storing your own water in your leaves) are both adaptations to plants growing in extreme hot and dry environments. I loved this combination of Kalanchoe pumila ‘Quicksilver’ and Senecio serpens at Eye of the Day Garden Center in Carpinteria, California.

kalanchoe-pumila-quicksilver-senecio-serpens-eye-of-the-day

This pairing of blue sticks (Senecio mandraliscae) with Scaevola aemula at the Montreal Botanical Garden was simple, yet dramatic.

scaevola-aemula-senecio-mandraliscae

And the gorgeous container below was in the former Vancouver garden of garden guru Tom Hobbs and Brent Beattie, owners of Vancouver’s Southlands Nursery.  It features Echeveria elegans, salmon-red Sedum rubrotinctum and silvery parrot feather (Tanacetum densum), along with astelia in the centre.

hobbs-echeveria-elegans-tanacetum-densum

Succulents have been used extensively over the years by Paul Zammit at the Toronto Botanical Garden. Check out this silvery monochrome masterpiece.

silver-succulents-toronto-botanical-garden

And finally, this gorgeous windowbox from the TBG, with its luscious mix of silver echeverias, aptenias, kalanchoes, senecios, rhipsalis and more, all enhanced by the dwarf Arctic willow hedging around it.

With that, I finish my monthly 2016 exploration of the garden paintbox. But not to worry!  2017 is a whole new ballgame, and there will be garden colour galore (plus the odd travel journal and personal reminiscence) throughout the coming year.

A November Wine Tasting

This is my month to explore that dark, rich, full-bodied, dowager great-aunt of ‘red’ – otherwise known as ‘wine’.  Or burgundy, if you like. Like its viticulture companion, a little wine in the garden goes a long way. Overdo it and you might not like the heavy feeling that results. But a little sip here and there adds depth and elegance to the garden. So let’s sample a few good vintages, shall we?

00-wine-flowers-leaves-the-paintbox-garden

In my part of the world, spring wines are quite common, given that the Lenten roses or hellebores are flowering in profusion. This is Helleborus ‘Blue Lady’.

01-helleborus-blue-lady-wine-flowers

There are a few excellent wine-red tulips for later in spring, like the lovely lily-flowered tulip ‘Burgundy’, below.

03-tulipa-burgundy

And I loved this combination of the bicolour Triumph tulip ‘Gavota’ and dark ‘Queen of Night’ at the Toronto Botanical Garden.

I know I might have included the late-flowered tulip ‘Queen of Night’ in my blog on ‘black’ flowers, but it often shows with more red. This is that sensuous tulip spangled through an uncharacteristically wild bulb planting in the very formal Jardin des Tuileries in Paris. Notice how the repetition of the dark colour carries your eye up through the various beds, unifying them and lending them a somewhat ‘designed’ feeling in keeping with the place.

 

05-tulipa-queen-of-night-tuileries

One of the more elegant little spring bulbs is snakeshead fritillary (Fritillaria meleagris). Apart from the checkered, wine-red species, there is a white form as well.

02-fritillaria-meleagris-wine-flowers

Of all the small trees for gardens, the biggest choice in red-leafed selections can be found in Japanese maples. This is the highly regarded Acer palmatum var. dissectum ‘Inaba-shidare’ at the Toronto Botanical Garden.

But the ubiquitous ‘Bloodgood’ Japanese maple (Acer palmatum) also puts on a beautiful wine-red show throughout summer, and colours beautifully to bright scarlet in fall.  Here it is with the Triumph tulip ‘Boston’ in the Mary Fisher Spring Garden at the Toronto Botanical Garden.

 

07-acer-palmatum-bloodgood-tulipa-boston

One of the best shrubs for adding deep wine-red colour to an herbaceous border is purple smokebush. There are a few cultivars but the most common is Cotinus coggygria ‘Royal Purple’. The trick is to cut it back to the ground, i.e. ‘coppice’ it, in spring. Here is ‘Royal Purple just emerging with tulips.

08-tbg-cotinus-coggygria-roya

Here is coppiced ‘Royal Purple’ a little later in the season with a lovely matching brushmark lily (possibly ‘Latvia’) in Bev Koppel’s wonderful garden at the Deep Cove Chalet Restaurant outside Victoria, B.C.

09-koffel-lilium-latvia-coppiced-cotinus

Here is coppiced Cotinus coggygria ‘Royal Purple’ with tropical Tibouchina urvilleana at the Conservatory Garden in New York’s Central Park.

10-cotinus-tibouchina-urvilleana-conservatory-garden-ny

And in Toronto horticulturist Frank Kershaw’s  garden, there is an entire symphony of wine colour around Cotinus coggygria ‘Royal Purple’, including shutters, window awning and dwarf Japanese barberry.

11-cotinus-frank-kershaw

Given all the hybridizing that’s occurred with heucheras over the past few decades, there are numerous selections with luscious leaves of burgundy and reddish-purple. At the Horticulture Centre of the Pacific outside Victoria, B.C., I adored this beautiful spring combination featuring Heuchera ‘Amethyst Mist’, Allium aflatunense ‘Purple Sensation’ and the dark-leafed ninebark Physocarpus ‘Diablo’ at rear.

12-heuchera-amethyst-mist-physocarpus-diablo-horticutlure-centre-of-the-pacific

Heuchera micrantha ‘Rachel’ is quite lovely.

13-heuchera-micrantha-rachel

And Heuchera ‘Pinot Noir’ has a name that fits our theme very nicely. It’s shown below frolicking with blue-flowered Gilia capitata.

14-heuchera-pinot-noir-gilia-capitata

One stunning peony is dark enough to be called ‘wine’, even if its actual name describes another favourite indulgence. Here is Paeonia ‘Chocolate Soldier’.

15-paeonia-chocolate-soldier

Though true-red irises have eluded hybridizers, there are many that come close to our November colour. Below is the heritage bearded iris ‘Col. Candelot’. Other deep-reds to check out are ‘Red at Night’, ‘Galactic Warrior’, ‘War Chief’, ‘Raptor Red’ and ‘Nebraska Big Red’, to name just a few.

16-iris-col-candelot

And what about this gorgeous thing? Meet Iris spuria ‘Cinnabar Red’.

17-iris-spuria-cinnabar-red

Though the mourning widow geranium (Geranum phaeum) is a little on the purplish side, I’ve included it here anyway. (And it’s a great bee flower!)

18-geranium-phaeum-mourning-widow

The breeders of the sweet William (Dianthus barbatus) below decided on a memorable name for their dark-flowered beauty. Meet ‘Heart Attack’, hanging out here with airy Allium schubertii at Wave Hill in the Bronx.

19-dianthus-barbatus-heart-attack-allium-schubertii-wave-hill

Early summer gives us masterworts (Astrantia major), and though many seem to be wishy-washy in their colouration, that’s not the case with ‘Hadspen Blood’, below, from Nori and Sandra Pope’s once glorious garden.

20-astrantia-major-hadspen-blood

I simply adore Knautia macedonica with its dark-red button flowers that flower from spring well into autumn. It is the zingiest zing you can have in a border (or meadow), and all the bees love it, too.

21-knautia-macedonica-toronto-botanical-garden

Daylilies (Hemerocallis) aren’t really my thing anymore, other than the dear old orange tawny lily (H. fulva) that I have given up trying to annihilate in my garden. That being said, there are lots of wine-colored selections to choose from, including the lovelies below.

Clockwise from upper left: Strutter’s Ball, Round Midnight, Regal Finale, Tuscawilla Blackout, Black Ice, Jungle Beauty, Starman's Quest, Jennifer Napier

Admittedly, Mexican hat (Ratibida columnifera) isn’t very showy, but it’s a fine choice for well-drained soil and a naturalistic garden.

23-ratibida-columnifera

Martagon lilies (Lilium martagon) are the epitome of elegance and will take light shade. Below is the fabulous ‘Sarcee’, named for a First Nation tribe in hybridizer Fred Tarlton’s province of Alberta. I photographed it in his astonishing collection at the Devonian Gardens near Edmonton.

For tough, low-maintenance perennials with wine-red leaves, you simply can’t beat sedums. Below is my array of some notable selections. The bees will thank you!

26-wine-leaved-sedum-array

We don’t always stop to observe the subtle colour changes that happen as flowers age beyond their prime. I loved this dreamy crimson-wine duo of Joe Pye weed (Eutrochium purpureum ssp. maculatum) and fountain grass (Pennisetum alopecuroides ‘Cassian’).

27-eutrochium-purpureum-ssp-maculatum-pennisetum-alopecuroides

Japanese barberry (love it or hate it) occupies a special place in the world of wine foliage, and its response to trimming makes it especially appealing in formal gardens. Without a red barberry, how could you possibly achieve the beautiful creation below, in the Knot Garden at Filoli Garden near San Francisco?  Along with the Berberis thunbergii ‘Crimson Pygmy’, we have dwarf lavender cotton (Santolina chamaecyparis ‘Nana’),  germander (Teucrium chamaedrys) and dwarf myrtle (Myrtus communis ssp. tarentina ‘Compacta’).

28-berberis-knot-garden-filoli

Though not particularly showy, the pineapple-scented, deep-red flowers of Carolina allspice (Calycanthus floridus), below, are intriguing – and they fit my category!

29-calycanthus-floridus-carolina-allspice

What about trees with dark-red leaves? One that is deservedly popular – and much smaller than its parent, almost a tall shrub – is weeping copper beech (Fagus sylvatica ‘Purpurea’), below.

30-fagus-sylvatica-purpurea-weeping-copper-beech

And I cannot go on without mentioning ‘Forest Pansy’ redbud (Cercis canadensis) – especially when it looks like this from underneath the canopy!

31-cercis-canadensis-forest-p

Now for some warm-weather wines: tender bulbs, tropicals and annuals.

A few of the pineapple lilies (Eucomis) are an interesting combination of olive and burgundy, like E. comosa ‘Oakhurst’, below.  Look at that dark-red stem. (‘Sparkling Burgundy’ is another with similar colouration.)

31-eucomis-comosa-oakhurst-pineapple-lily

Although they can look parkimental (park+regimental) grown in rows or Victorian-style bedding, many cannas have beautifully marked leaves and, in the right spot, add a luscious touch. Here is ‘African Sunset’ canna lily (Canna australis).

37-canna-african-sunset

Speaking of the ‘right spot’, in Bev Koffel’s garden, a reddish canna and the deep-burgundy succulent Aeonium arborescens ‘Zwartkop’ add rich notes to an elegant urn.

41-aeonium-zwartkop-bev-koffel

Do you grow dahlias? If you like dark and dramatic, look no further than ‘Black Knight’.

33b-dahlia-black-night

Perhaps no species offers more possibilities in the wine spectrum than the foliage plant coleus (Plectranthus scutellarioides, formerly Solenostemon, formerly Coleus blumei). I was enchanted by the way the gardeners at Toronto’s Spadina House worked ‘Wizard Mix’ coleus into their late summer plantings.

32-plectranthus-wizard-velvet-red-china-asters

35-Plectranthus scutellarioides 'Big Red Judy'

Though it’s not hardy in my part of the world, Pennisetum setaceum ‘Fireworks’ is a fabulous, variegated, dark-red grass to add movement and colour to the summer garden.

36-pennisetum-setaceum-fireworks

I’m a frequent visitor to the Montreal Botanical Garden, and I loved seeing these burgundy-leaved tropicals against a yellow and gold three-panelled screen there a few years ago. From left rear are red spike (Amaranthus cruentus), rubber tree plant (Ficus elastica ‘Burgundy’), calico plant (Alternanthera dentata ‘Purple Knight’) and ‘Carmencita’ castor bean (Ricinus communis).

38-wine-colored-foliage-montreal-botanical-garden

Here’s a look at the flowers of ‘Carmencita Bright Red’ castor bean (Ricinus communis). (Caveat emptor. Do be aware that this plant’s seeds contain one of the deadliest toxins known to man, ricin.  Just a few salt-sized grains of purified ricin can kill an adult.)

39-ricinus-communis-carmencit

When we visited Nancy Goodwin’s Montrose Garden in Hillsborough, NC, a few years ago, spectacular and unexpected colour combinations were everywhere. I did enjoy this red-leaf hibiscus (Hibiscus acetosella) with orange dahlias.

40-hibiscus-acetosella-dahlia-montrose

In my own garden, I experiment each year with the contents of the six containers on the lower landing of my sundeck. One summer, below, I tried ‘Sweet Caroline Red’ sweet potato vine (Ipomoea batatas) with  Anagallis ‘Wildcat Orange’. (The truth is it looked better in June than it did in August, since the anagallis petered out and the chartreuse-leaf pelargoniums were underwhelming, but the sweet potato vine thrived.)

42-ipomoea-batatas-sweet-caroline-red

Speaking of pelargoniums, ‘Vancouver Centennial’ is a real winner, with its bronze-red foliage.

43-pelargonium-vancouver-centennial

One of the best spiky ‘centrepiece’ annuals is Cordyline australis ‘Red Star’, seen here in a pot at the Toronto Botanical Garden. Just look how its deep tones are picked up in those colour splotches on the luscious ‘Indian Dunes’ pelargonium.

44-cordyline-red-star-toronto-botanical-garden

And hello ‘grains-as-ornamentals’! This was redspike (Amaranthus cruentus) with slender vervain (Verbena rigida) and ‘Lemon Gem’ marigolds (Tagetes tenuifolia) in a fabulous planting one year at Vancouver’s Van Dusen Botanical Garden.

45-amaranthus-cruentus-tagetes-verbena-rigida-van-dusen

Speaking of edibles, you can’t get find a more beautiful, wine-leafed edible than this beet:  Beta vulgaris ‘Bull’s Blood’ with nasturtiums and chartreuse ‘Margarita’ sweet potato vine (Ipomoea batatas).

46-beta-vulgaris-bulls-blood

And my last sip for our November wine tasting is a fine, full-bodied claret – yes, ‘Claret’ sunflower (Helianthus annuus).

47-Helianthus-annuus-Claret

Whew! ‘Wine-ding’ down now, that takes me through eleven months in my 2016 paintbox. Stay tuned for December and some lovely silver ‘belles’.

Orange: Three Fruits & a Fish – Part Two

In my last colour blog Orange: Three Fruits & A Fish – Part One, we explored some beautiful orange-flowered perennials. Here I’ll offer up some hardy roses, shrubs and vines with orange blossoms or colourful orange fruit, then an assortment of orange-flowered annual and tropical flowers.

Shrubs & Vines

Flowering quince (Chaenomeles sp.) is one of those spring shrubs that appear in April or May, its salmon or tangerine blossoms emerging on spined branches to outshine even colourful tulips and daffodils, and attracting early bees to its pollen-rich stamens. Old-fashioned and much-planted in the 1950s, you don’t see flowering quince in many contemporary gardens today, which is a pity. The ones I’ve photographed have been in the cemetery, like this C. x speciosa at Mount Pleasant Cemetery… 4-chaenomeles-speciosa-2

…or in a botanical garden, like this exquisitely-pruned, little specimen nestled against a rock in the Japanese Garden at Montreal Botanical Garden.4-chaenomeles-japonica3

Spring is also the season for wonderful rhododendrons, and we can find some good orange-flowered examples. For fifty years now (since 1957), the ‘Lights’ breeding program at the Agricultural Experiment Station of the University of Minnesota has produced some rugged, hardy azaleas (botanically rhododendrons) in a spectacular range of colours. ‘Spicy Lights’ was bred in 1987, and is a beautiful, rich salmon-orange with yellow blotches.4-rhododendron-spicy-lights

I love strolling along the Rhododendron Walk at Vancouver’s Van Dusen Gardens in May, when the Japanese azaleas are in bloom. Though it’s not hardy for us here in Toronto, Rhododendron molle. ssp. japonicum (USDA Zone 6) is one of my favourites there, especially with its contrasting groundcover of blue Spanish bluebells (Endymion hispanicus).4-rhododendron-molle-endymion-hispanicus-van-dusen-gardens

Honeysuckle vines are super-hardy, bring hummingbirds, and look fabulous with their orange & scarlet blossoms spangled over a wall or fence. This is Lonicera ‘Mandarin’, developed at the University of British Columbia. 4-lonicera-mandarin

And this is old-fashioned Lonicera x brownii  ‘Dropmore Scarlet’, developed as a cross between L. sempervirens and L. hirsuta in the 1950s by the famous breeder Frank Skinner in Dropmore, Manitoba.  It can grow to 12 feet (4 metres) when happy.  Note the eye-pleasing effect of growing an orange-flowered vine on a brick wall – and orange brick is a subject all its own, a backdrop that can make or break a garden vignette. 4-lonicera-x-brownii-dropmore-scarlet-on-brick-wall

One of the bigger North American native vines (to 30 feet or 10 metres) is trumpet creeper (Campsis radicans), but it must have a strong support. As its Wikipedia page says:  “The vigor of the trumpet vine should not be underestimated. In warm weather, it puts out huge numbers of tendrils that grab onto every available surface, and eventually expand into heavy woody stems several centimeters in diameter. It grows well on arbors, fences, telephone poles, and trees, although it may dismember them in the process. Ruthless pruning is recommended.”  Hummingbirds and bees love trumpet creeper flowers. 4-campsis-radicans

Roses

Not being a rosarian, I can only suggest a few orange roses that come recommended. One is ‘Westerland’, a large-flowered, repeat-blooming, upright shrub or climber that can reach 12 feet (4 metres). Its highly-fragrant flowers are produced continuously from June to frost. Bred by Kordes in 1969, it is the recipient of an AGM (Award of Garden Merit) from England’s Royal Horticultural Society.  This is ‘Westerland’ at New York Botanical Garden’s fabulous Peggy Rockefeller Rose Garden.

4-rosa-westerland2

Another tall, fragrant climber with pale, apricot-orange blossoms is ‘Alchymist’.

4-rosa-alchymist

David Austin Roses has bred many lovely apricot- and peach-flowered shrub roses. Below is ‘Lady of Shalott’ (4-5 feet tall), an AGM winner and considered to be one of the hardiest and most disease-resistant of the English roses.

4-rosa-lady-of-shalott

There are too many shrub roses and floribundas with orange flowers to mention, but I very much like the award-winning floribunda ‘Fellowship’.

4-rosa-fellowship1

Orange Fruit

Apart from the orange, bronze and apricot hues that many deciduous trees and shrubs take on in autumn (see my blog on orange fall colour here), there are many with jewelled orange fruits in late summer and fall, too. One of the prettiest is ‘Afterglow’ winterberry (Ilex verticillata), shown here with purple-fruited beautyberry (Callicarpa dichotoma ‘Early Amethyst’).

4-ilex-verticillata-Afterglow

And I must mention firethorn (Pyracantha coccinea), which features a number of orange-fruited cultivars, including ‘Orange Glow’.

Annuals & Tropicals:

Now we get into the fun part of my orange treatment: the flowering annuals, tender bulbs and perennials, and tropical plants. Let’s start with the newish dark-leafed little Begonia ‘Sparks Will Fly’.

6-begonia-sparks-will-fly

My pal and container whiz, Toronto Botanical Garden horticulturist Paul Zammit, worked this one into a spectacular urn creation, along with Begonia boliviensis and orange-toned cannas, lantanas and coleus.

6-begonia-sparks-will-fly-in-container-toronto-botanical-garden

And if you had a peek at that container blog, you’ll see that Paul does love a little orange, including the row of window boxes, below, featuring kitchen herbs parsley and sage with a mix of Calibrachoa MiniFamous iGeneration Orange and Can Can Terracotta with the grasses Hakonechloa ‘All Gold’ and Carex buchananii.

6-calibrachoa-minifamous-igeneration-orange-can-can-terracotta-toronto-botanical-garden

Hardworking calibrachoas (million bells or mini-petunias) have become mainstays of annual container design in the past decade or so. I loved this combination of Calibrachoa ‘Superbells Peach’ and ‘Superbells Blue’ with ‘Purple Wave’ petunias in a window-box in Niagara-on-the-Lake, Canada.

6-calibrachoa-peach-and-magenta

And can you say “coral” (i.e. salmon)? The fabulous duo shown below is Calibrachoa ‘Superbells Coral Punch’ and Verbena ‘Superbena Coral Red’.

6-verbena-superbena-coral-calibrachoa-superbells-coral-punch

I’ve been a fan of the ‘Profusion’ series of zinnias since their launch in the 1990s.  I especially loved the way Vancouver’s Van Dusen Gardens scattered Zinnia ‘Profusion Orange’ through this intermingled planting with Salvia patens ‘Cambridge Blue’, bunny tail grass (Lagurus ovatus) and purple verbena (V. rigida).

6-zinnia-profusion-orange-van-dusen-gardens

I’ve included Zinnia ‘Profusion Orange’ in my own container on the deck at Lake Muskoka, below, along with yellow and apricot African daisies (Osteospermum ‘Symphony Series’) and orange nasturtiums (Tropaeolum majus).

6-zinnia-profusion-orange-tropaeolum-osteospermum

African daisies or osteospermums come in a range of orange shades. When I was at wonderful Chanticleer Garden in Wayne, Pennsylvania, I was entranced by the combination below of apricot-flowered Osteospermum ‘Zion Orange’ with Diascia ‘Flirtation Orange’, caressed by the grassy, bronze-orange blades of Carex testacea.

6-carex-osteospermum-chanticleer

Nasturtiums, of course, offer a serious orange jolt of their own. Here is Tropaeolum majus ‘Alaska’ with the signet marigold Tagetes tenuifolia ‘Tangerine Gem’. And guess what? Both are edible!

6-tropaeolum-majus-alaska-tagetes-tangerine-gem

And there’s a plus to nasturtiums: hummingbirds love them.

6-tropaeolum-majus-with-hummingbird

Speaking of hummingbirds, you will almost certainly attract them to your containers if you include one of their favourite flowers, hummingbird mint or agastache. This is Agastache ‘Kudos Coral’, and it’s a good hummer lure.

6-hummingbird-on-agastache-kudos-coral

I also love the little Agastache ‘Apricot Sprite’ – it’s perfect for pots and hanging baskets, and I’ve even found that it reseeds in my USDA Zone 5 containers.

6-agastache-apricot-sprite

Back to marigolds, I’ve never been a fan of the big African numbers (Tagetes erecta), so stiff and regimented they seem to be suited only to park plantings. But I’d certainly love to try the willowy (18 inch – 45 cm) Tagetes ‘Burning Embers’, which I found in my friend Marnie White’s garden. Some seed sources refer to this as a selection of a species Tagetes linnaeus, (and say something about it being found in Linnaeus’s Uppsala garden) but that binomial doesn’t seem to be valid.  I assume it’s simply a good form of Tagetes patula.

6-tagetes-patula-burning-embers

When I first saw orange petunias, I was taken aback as they’re a brave, new colour in those old-fashioned annuals.  The one below is ‘Sun Spun Orange’ – what a fabulous container plant it would be!

6-petunia-sun-spun-orange

Fuchsias can be orange, too, and are a good container solution for partly shaded spots. The creative combination, below, features Fuchsia ‘Gartenmeister’, Lantana ‘Landmark Sunrise’, and purple browallia, along with other annuals.

6-fuchsia-gartenmeister-lantana-browallia

Lantanas come in many shades of peach, apricot and orange and, depending what else is in bloom, offer sweet foraging for butterflies.

6-lantana-monarch-butterfly

Another edible flower that’s a fixture in kitchen gardens is pot marigold or Calendula officinalis.  It comes in singles, doubles and shades of yellow, gold and orange. I liked this simple combo with chives (Allium schoenoprasum).

6-calendula-chives

Speaking of kitchen gardens, have you noticed the great breeding work that’s being done with amaranths to take them out of the grain field and transform them into bold standouts in the ornamental border? This is Amaranthus ‘Golden Giant’.

6-amaranthus-hypochondriacus-golden-giant

And this is what it looks like backing up purple anise hyssop (Agastache foeniculum).

6-amaranthus-hypochondriacus-golden-giant-agastache-foeniculum

Gloriosa daisies are deservedly popular and add a little Hollywood pizzazz to common old blackeyed susans. Of the many variations in colour, likely the best selection for adding bronze-orange to the garden (there’s no pure orange) is Rudbeckia hirta ‘Cappucino’.

6-rudbeckia-hirta-cappuccino

This is how ‘Cappucino’ looks with ‘Lemon Gem’ marigolds and purple Verbena rigida in a bed at Van Dusen Gardens. Pretty nice, right? And it’s easy to grow from seed.

6-rudbeckia-hirta-cappuccino-van-dusen

Now, if you want a true-orange ‘daisy’ flower, you need only choose butterfly-friendly Mexican sunflower (Tithonia rotundifolia), either the straight species – which can grow 4-6 feet tall   shown at left and middle, below, or a dwarf form such as ‘Fiesta del Sol’, shown at right with Salvia farinacea.

6-tithonia-rotundifolia-mexican-sunflower

The most impressive ‘daisies’ of all are sunflowers (Helianthus annuus), and though none are pure orange, you can find some burnt-orange selections like ‘Evening Colors’, ‘Earthwalker’, ‘Crimson Queen’ and ‘Autumn Beauty’.

6-helianthus-annuus-orange-flowers

I won’t bore you with orange-flowered pelargoniums (border geraniums) because we’d be here all night, but just a mention of two with stunning foliage. The first is ‘Indian Dunes’, below, – and I do like those salmon-orange blooms.

6-pelargonium-indian-dunes

The second is ‘Vancouver Centennial’ – invaluable for its wine-brown leaves and delicate orange flowers.

6-pelargonium-vancouver-cent

Tropical milkweed (Asclepias curassavica) has become popular to grow as annual flower in recent years as more gardeners look to attract monarch butterflies to their gardens. Like all milkweeds, its foliage is food for monarch caterpillars, and it does look pretty in combination with plants like annual Verbena bonariensis, below.

6-asclepias-curassavica-verbena-bonariensis

Zingy gomphrenas have seen their popularity surge – and  they’re fabulous as cut flowers and dried flowers, too. If you want to try one in orange, search out Gomphrena ‘QIS Orange’, shown below with purple Ageratum houstonianum.

6-gomphrena-qis-orange-ageratum

Ursinia anthemoides ‘Solar Fire’ veers a little from apricot-orange towards gold, but I’m including it here because I think it’s an annual that should be grown more. It looked lovely at the Montreal Botanical Garden with Echium vulgare ‘Blue Bedder’.

6-ursinia-anthemoides-solar-fire-echium-blue-bedder

I’m finishing my book-length (!) dissertation on orange flowers with a handful of dahlias. Tender tubers, they are easily grown in warm soil in spring and must be stored indoors for winter. Goodness knows there are myriad dahlias of all shapes and sizes in orange, but the array below shows some of my favourites, including the aptly-named cactus dahlia ‘Bodacious’, top; and below, two more modestly-sized border varieties: the bee-friendly ‘Bishop of Oxford’ left, and ‘Pooh’, right.

Orange Flourishes

Woman does not live by Flora alone, of course. There are other ways to bring the colour orange into the garden without actually growing it. When I visited gardens in Portland, Oregon, I was delighted to see these whimsical orange accessories in Nancy Goldman’s funky backyard lair.

5-nancyland-orange-gaden-accessories

And do you agree with me that this Toronto garden just amped up the cool factor with bright orange chairs beside all those bobbing purple alliums?

5-orange-chairs-purple-flowers

But really, orange in the garden doesn’t have to be furniture, and it doesn’t have to be splashy. It can be as tiny and perfect as a fanciful glass bird sailing away on an ocean of frothy foliage. (Thank you Michael Renaud of Toronto’s Horticultural Design.)

And on that final “October is my Orange month” note, I will sail away into November, when we shall reconvene in The Paintbox Garden for a little “wine-tasting”. I’ll bring out some of my finest burgundies for you to sample.

Orange: Three Fruits & a Fish – Part One

Well, it’s now October and I resolved back on January 1st to devote my Paintbox blog this month to the colour orange.  Or, as I’ve called it in my title, ‘three fruits and a fish’, which pokes a little fun at the way the English language learned to describe colours, long before Isaac Newton first focused a prism on sunlight and conjured up the ‘visible light’ spectral rainbow in his college room.

0-newtons-prism

“Three fruits and a fish” is not a balanced diet, but a plateful of related colour:  orange, peach, apricot and salmon.  (And in the interest of trivia, did you know that the fruit orange is classified as a hesperidium or modified berry? I thought not! Peaches and apricots, of course, are drupes or simple stone fruits. You’re welcome.) We all know what a naval orange or sockeye salmon flesh looks like, but what distinguishes peaches and apricots? Well, Wiki defines apricot as a “pale, yellowish-orange color” (or, as I say, halfway from orange to gold), and  peach as a “light moderate to strong yellowish-pink to light orange colour” (my emphasis on the pink here, but without sufficient blue pigment to tip it completely into that candyfloss hue).

0-peach-apricot

And what colour is salmon? Wiki says it’s “a range of pale pinkish-orange to light pink colors, named after the color of salmon flesh.” I would disagree with the “pale” part, unless you’re talking about spring salmon J. (Then again, Wiki has this painful, hair-splitting dissertation further down the page: “The color light-salmon is displayed at right. This is a color that resembles the color salmon, but is lighter, not to be confused with dark salmon, which resembles salmon pink but is darker than salmon pink and much darker than light salmon.” Confused yet?)  I think of salmon as being a rich colour, as shown in the tropical plants Acalypha wilkesiana and Abutilon, below, in a container at the Toronto Botanical Garden…

0-salmon-acalypha-wilkesiana-abutilon-toronto-botanical-garden

Placing my colour arrays together, below you can see more clearly the difference in (clockwise from top left): orange, salmon, peach and apricot.

Looking at the artist’s colour wheel, below, which is essentially a rainbow curved into a circle to illustrate in a visual way the relationships between spectral colours, we see 6 hues marked with a letter. The three marked “P” are defined as primary colours: red, yellow, blue.  By combining equal parts of those primary colours with their neighbouring primary colour, we come up with the secondary colours shown and labelled “s”. It is more complicated than that (and of course there are tertiary colours and darker shades and lighter tints) but the point I’m making is that if our gardens were paintings, the visually pleasing ‘complementary contrast’ to the secondary colour orange is the primary colour blue.  Keeping in mind that that artist’s colour wheel is just one of several ways of ‘organizing’ colour (the primary colours of light are an entirely different subject), on my power point slide below, orange wallflowers (Erysimum) are perfectly paired with deep blue forget-me-nots (Myosotis sylvatica).

0-x-colour-wheel-complementary-contrasts

And that’s not to say that orange ‘Beauty of Apeldoorn’ tulips, below, wouldn’t look as lovely with yellow or dark pink flowers as neighbours, but the relationship of the colours blue and orange is inherently a pleasing one to our eyes.  And from long observation, I’d add that orange flowers also look good paired with violet, purple and lavender blossoms as well.

0-x-tulipa-beauty-of-apeldoorn-forget-me-nots

Because I love the colour orange and have spent a lot of time observing this colour in gardens and nature, I’ve collected photos of myriad plants with orange flowers (and colour companions for those), as well as plants with orange berries and orange fall leaf colour.  (Read my blog on orange autumn leaves here.)  I’ve even assigned orange-coloured plants to their growth type and seasons, below.

Spring Bulbs 

So let’s explore orange in the garden beginning with some of my favourite spring blossoms, then hardy summer bulbs and perennials.  In my next colour blog, I’ll talk about orange-flowered and orange-leafed roses, shrubs, tropicals and annuals. And let’s begin – as the flowering year does – with crocuses. Who doesn’t love a good apricot-orange crocus, like C. x luteus ‘Golden Yellow’?  Honey bees do, I can assure you.

1a-crocus-x-luteus-golden-yellow

I’m a sucker for perfumed hyacinths (Hyacinthus orientalis) – I buy a few dozen every couple of years, and love them even better when their form relaxes in years 2 and 3. (But don’t count on them hanging around forever.) If I were planting hyacinths with little blue bulbs like striped squill (Puschkinia scilloides), I’d definitely choose peach-orange ‘Gipsy Queen’, below.

1a-hyacinthus-orientalis-gipsy-queen

Then there are daffodils. Have you grown any split-corona or butterfly types? One of the most spectacular is also one of the most pronounced “orange” daffs. Meet ‘Orangery’.

1a-narcissusorangery

Since I’m a gardener who enjoys naturalistic, meadow-style gardening, I can’t say I’ve ever been a great fan of the big crown imperial fritillaries – a bit too stiff for me. But you must admit that Fritillaria imperialis ‘Rubra Maxima’ would make a splash, especially in a formal garden.

1a-fritillaria-imperialis-rubra-maxima

Orange tulips like lovely ‘Beauty of Apeldoorn’ pictured above are fairly common, and personally, I love planting them with pink tulips, because winter is just too long and cold not to celebrate with a riot of warm colour in spring.  Here are some of my other orange favourites: 1 – Orange Emperor, 2 – Daydream, 3 – Irene Parrot, 4 – El Niño, 5 – General deWet, and 6 – Ballerina.

1a-orange-tulips

The lily-flowered tulip ‘Ballerina’ deserves special mention. It really is a wonderful dancer.

1a-tulipa-ballerina

And I cannot leave tulips without paying tribute to one of the peacocks of the spring bulb world: the parrot tulip. This is ‘Salmon Parrot’.  It won’t last long – it’s definitely not a ‘perennializer’ – but if you’re this stunning, you don’t need to hang around forever.

1a-tulipa-salmon-parrot-1

Hardy Bulbs

Hardy lilies (Lilium) in shades of orange are a dime-a-dozen too, and I’ve gathered a few combinations featuring purplish perennials.  There’s old fashioned speckled tiger-lily (Lilium lancifolium), here consorting fetchingly with ‘Fascination’ Culver’s root (Veronicastrum virginicum).

1-lilium-lancifolium-veronicastrum-fascination

And one of my newest favourites, Lilium henryi, shown here with hoary skullcap (Scutellaria incana) in the Piet Oudolf-designed Seasonal Border at the New York Botanical Garden.

1-lilium-henryi-scuttelaria-incana
Should you desire some knock ‘em dead perfume in the summer garden, you can always plant a few ‘African Queen’ trumpet lilies. Mmmm…..

1-lilium-african-queen

But for the world’s most delicate, elegant lilies, you need a martagon or two, especially in conditions of light shade. On the left, below, is ‘Sing Out’, on the right ‘Burnt Orange’.

1-lilium-martagon-sing-out-burnt-orange

Where it’s hardy (Zone 6), Crocosmia ‘Emily McKenzie’, a corm that is planted in early spring, is a wonderful deep-orange hit for the garden. And like all crocosmias, it’s a hummingbird favourite. I loved the double-header below at Vancouver’s Van Dusen Gardens with ‘Emily McKenzie’ in the foreground and an orange Helenium autumnale (perhaps ‘Rubinzwerg’) in the rear, sandwiching a white echinacea.

1-van-dusen-crocosmia-echinacea-helenium

Stately foxtail lilies (Eremurus), though considered a ‘fleshy root’ rather than a bulb, are nonetheless often sold in autumn along with bulbs.  They can be orange, white, yellow and peach and add a gorgeous vertical note to early summer plantings (plus bees adore them). I thought this joyous planting of Eremurus ‘Cleopatra’ with corn poppies (Papaver rhoeas) in a mixed meadow planting of annuals and perennials at Chanticleer Gardens  in Wayne, PA was one of the prettiest combinations I’ve seen.

Here it is again, showing the entire Rock Ledge Garden at Chanticleer. That’s dark purple Salvia nemorosa ‘Caradonna’ at the bottom.1-eremurus-rock-ledge-chanticleer

 

Perennials

Letrozole is an oral non-steroidal drug to treat hormonally responsive breast cancer which may surface after surgery. buy viagra sale cialis generika 10mg raindogscine.com A subsequent survey depicts that PE condition affects 31% of men in their fifties, 30% in their early 30s and 40s is soaring.

What about orange-flowered perennials? Let’s begin with a few orange-flowered perennials for spring.  If you haven’t followed the exploding popularity of geums in the past decade or so, you’re missing a great group of plants.  Below is yet another fruit for our colour plate: mango! In the form of Geum ‘Mango Lassi’.

2-geum-mango-lassi

While on one of my late spring visits to Vancouver’s Van Dusen Gardens, I was wowed by this mass waterside planting of Euphorbia griffithi ‘Fireglow’.

2-euphorbia-griffithii-fireglow-van-dusen

And there are beautiful orange primulas for damp places in spring. Look for Primula bulleyana, below….

2-primula-bulleyana-1

… and the rich orange form of cowslip (Primula veris).

1-primula-veris-orange-form

The best peonies can do in the orange department is coral, which is just a teensy bit redder than salmon. But there are some beauties, including the four below, clockwise from upper left: ‘Constance Spry’, ‘Coral Sunset’, ‘Coral Supreme’ and ‘Lorelei’.

2-paeonia-coral-shades

There are some luscious peaches in the Itoh Peony group (hybrids between tree peony and herbaceous peony), including ‘Kopper Kettle’, below, with Salvia nemorosa ‘May Night’.

2-paeonia-kopper-kettle-salvia-may-night

The genus Papaver boasts many orange-flowered species, but none are more flamboyant than old-fashioned Oriental poppy. This is Papaver orientale ‘Prince of Orange’.

2-papaver-orientale-prince-of-orange

And you will always find bees and hoverflies on wonderful little Moroccan poppy (Papaver atlanticum ‘Flore-Pleno), which is surprisingly hardy (USDA Zone 5) and easy to grow in all soils.

2-papaver-atlanticum-flore

Bearded irises are the prima donnas of the early summer garden, and you can find them in the most wonderful shades of peach, bronze and clear orange, like the tall bearded ‘Orange Impact’, below.

2-iris-x-germanica-orange-impact

I was intrigued to find beautiful copper iris (Iris fulva) growing on New York’s High Line.  Honey bees had found it too, but its natural pollinators in the Mississippi Valley are hummingbirds. This orange-flowered member of the Louisiana Iris group likes damp (even wet), slightly acidic soil and is supposedly hardy to USDA Zone 5.

2-iris-fulva-high-line

Verbascums can be found in apricot-orange (‘Helen Johnson’ among others), but this delicate June pairing in pale peach caught my eye at Toronto’s Casa Loma: Verbascum ‘Southern Charm’ and Sicilian honey lily (Allium siculum, formerly Nectaroscordum).

2-verbascum-southern-charm-allium-siculum

One genus that’s seen a lot of hybridizing in recent decades is red-hot poker or torch lily (Kniphofia). Since they grow naturally in hues of orange or yellow, there is an abundance of choice here.  I loved this fun mingling of Allium ‘Lucille Ball’ and Kniphofia ‘Flamenco’ at Chanticleer, in Wayne, PA.

2-kniphofia-uvaria-flamenco-allium-lucille-ball-chanticleer

And don’t forget about heucheras; they’re a treasure trove of peach and bronze-orange foliage possibilities.  Here’s Heuchera ‘Caramel’ with dwarf Kniphofia ‘Mango Popsicle’.

2-kniphofia-heuchera-caramel

Daylilies, of course, offer a motherlode of orange choices, not just in orange, shown in a few samples below (Clockwise from top left:  Hemerocallis fulva ‘Kwanso’, Kansas, Challenger, Lady Lucille, Rosalind, Furnaces of Babylon)….

2-hemerocallis-array-orange

…. but there are loads of peach (left) and apricot (right) cultivars, below, too.  And note that in the daylily world, “lavender” is often (peachy) wishful thinking. (Top, left to right: Uptown Girl, Strawberry Candy, Chicago Peach, Second Glance; Middle: Empress Josephine, Designer Jeans, Scatterbrain, Ellen Christine; Bottom: Lavender Illusion, Lavender Patina, Brookwood Double Precious, Fan Dancer).

2-hemerocallis-array-peach-apricot

Daylilies are so prolific and varied in colour, they can be forgiven their need for constant deadheading and propensity to browning foliage in late summer, etc.  So they’re best paired with other plants, like this duo at the New York Botanical Garden: Hemerocallis ‘Poinsettia’ with balloon flower (Platycodon grandiflorum).

2-hemerocallis-poinsettia-platycodon-new-york-botanical

The vast daylily collection at Montreal Botanical Garden offers lots of brilliant ideas for partnering, including this bronze-orange ‘Chelsey’ helenium (Helenium autumnale) with lovely Hemerocallis ‘Cherokee Pass’.

2-hemerocallis-cherokee-pass-heleniumchelsey

One of the best perennials for dry gardens is hybrid blanket flower (Gaillardia x grandiflora). Provided you keep it deadheaded, it will flower from early summer well into autumn, and the bees will thank you. Though most are bicoloured red-yellow or red, I have grown a beautiful orange one: G. x grandiflora ‘Tokajer’. It lasted for three years or so, and I missed it terribly when it didn’t come back one spring, possibly after a winter without sufficient snow cover.

2-gaillardia-x-grandiflora-tokajer

I’ve written before about my favourite orange-flowered perennial, butterfly milkweed (Asclepias tuberosa), which is simply unparalleled for attracting pollinators (including the monarch butterfly, which uses it as a larval food).

2-asclepias-tuberosa

And it’s fun if you want to create a little heat, colour-wise, as I’ve done below, pairing it at my cottage with bright-red ‘Firebird’ echinacea.

2-asclepias-tuberosa-echinacea-firebird

Speaking of heat, orange flowers are often the backbone of hot-coloured schemes in the garden, whether paired with reds and golds, as with Echinacea ‘Tangerine Dream’ and ‘Secret Glow’, below….

2-echinacea-tangerine-dream-secret-glow

… or with hot-pinks, below. On the left is butterfly milkweed with the pink ‘Orienpet’ lily ‘Robina’, on the right is the double daylily Hemerocallis ‘Kwanso’, with a bright pink summer phlox.

2-asclepias-tuberosa-lilium-phlox

That’s a good first look at hardy orange bulbs and perennials. Next time, we’ll explore orange-flowered shrubs, annuals and tropicals, and a few design touches to add a little orange punch to your garden.

Beguilingly Brown in the Garden

“Brown in the garden”. Remember my January resolution to blog about every colour for all of 2016? Well, it’s September and I’ve delayed writing about brown as long as I could….

Brown Flowers & Leaves-ThePaintboxGarden

No, “brown in the garden” is not a phrase you often hear, unless it’s wondering what to do with those Japanese maple leaves that are curling up and turning brown in summer (uh-oh).  Or the white pine needles that are turning brown in October (they’re getting ready to fall silly… no evergreen is truly ever-green.)

In the winter, you might notice bronze oak leaves remaining on trees, even through the snowiest and coldest weather.  That is a function of tannins that remain in the leaves once chlorophyll breaks down, protecting and preserving them in the same way an old-fashioned ‘tanner’ would use these substances to turn animal hides into leather.  This tendency to hang onto the twig as a brown leaf after most deciduous trees have lost their leaves is called marcescence.  Beeches, below, also exhibit marcescence, and their winter leaves can be quite fetching in the garden..

beech-leaves

I love this winter combination of columnar beeches (Fagus sylvatica ‘Atropurpurea’) and switch grass (Panicum virgatum) at the Toronto Botanical Garden.

fagus-sylvatica-atropurpurea

Many warm-season grasses also retain tannins in the leaf and enough structural integrity to stand upright through winter weather. Shown below in snow is switch grass (Panicum virgatum), but you may note this strong winter presence in maiden grass (Miscanthus), feather reed grass (Calamagrostis), fountain grass (Pennisetum) and northern sea oats (Chasmanthium) as well.

panicum-virgatum

Toronto’s Music Garden relies on ornamental grasses to provide much of its interest for the long winter months.

grasses-music-garden

Brown seedheads also have their own charm, and many look beautiful against snow. This is anise hyssop (Agastache foeniculum ‘Blue Fortune’) consorting with a grass in winter.

agastache-foeniculum-blue-fortune

Purple coneflower seedheads (Echinacea purpurea) persist very well through winter, and feed hungry birds as well.

echinacea-seedheads

Even in the gardening season, flowers that turn brown add a textural note to plantings.  In my own cottage meadows, I love the September shaving-brush seedheads of New York ironweed (Vernonia noveboracensis).

vernonia-noveboracensis-seedheads

These are the seedheads of Phlomis tuberosa ‘Amazone’, with the fading flowers of echinacea. Not surprisingly, this duo is in the Entry Border of the Toronto Botanical Garden – a border designed by Piet Oudolf, whose philosophy is to create a meadow-like tapestry of plants that lend beauty even when out of bloom.

And look at these giant alliums, also in the entry border at the TBG. Of course they were beautiful when they were rich violet-purple, but I do love them as brown seedheads consorting with the rest of the plants a few weeks later.

Speaking of the Toronto Botanical Garden, I spend so much time there, chronicling the changes in the various gardens, but especially in Piet Oudolf’s Entry Border, that I’ve come to appreciate the plants that persist beyond their starring roles. So I’ve made a video to show the function that “brown” fulfills as a substantive colour in autumn and winter, after the colourful flowers have faded. There are many plants shown in these images, but especially good for persistence of seedheads are Liatris, Echinacea, Achillea, Stachys, Astilbe and, of course, all the ornamental grasses. Have a look……

Piet Oudolf also designed the plantings at the High Line, where brown is a colour, too. Below is a pink astilbe in the process of turning bronze, then buff, making it the perfect colour companion for the blackeyed susans.

Lovely as they are in the winter garden, many grasses also have spectacular brown flowers that create lovely colour combinations in the summer garden, too, like this fluffy brown cloud of (Deschampsia caespitosa) with airy sea lavender (Limonium latifolium), also in the border designed by Piet Oudolf.

And here it is softening purple coneflowers (Echinacea purpurea) at the Royal Botanical Garden in Burlington, Ontario.  Doesn’t that little cloud of brown add a grace note to that scene?

This is feather reed grass (Calamagrostis acutiflora ‘Karl Foerster’) with blue Russian sage (Perovskia atriplicifolia) – demonstrating that blue and (golden) brown make lovely dance partners.

Speaking of blue and brown, this is a very good combination:  Amsonia ‘Blue Ice’ with Heuchera ‘Caramel’.

heuchera-amsonia-blue-star

Heucheras, of course, have been bred over the past few decades to produce a fabulous range of colours, many of which veer towards brown. I love the rich tones of ‘Mahogany’, below.

Even some evergreens can be called brown, like this weird little arborvitae, Thuja occientalis ‘Golden Tuffet’ (which isn’t even dead!)

Many tropical plants seem to exhibit brownish tones. For example, luscious Canna ‘Intrigue’, here with coleus at the Toronto Botanical Garden….

For instance, Kamagra, the herbal male enhancement pills can be utilized by you to cover your medical costs. http://downtownsault.org/wp-content/uploads/2018/02/04-13-16-DDA-MINUTES.pdf online levitra These discount samples of viagra coupons and promo codes are going to trap by ED, but if you notice that your penile organ is as large and strong as you want or as little. Still others expect discount online viagra that parenthood will become a means of providing protection and care for themselves in their old age. This unfortunate result appears due to cheapest viagra inconsistent or insufficient blood flow. canna-intrigue-toronto-botanical-garden

…. and that strange multi-colored tropical shrub copperleaf (Acalypha wilkesiana), with its patchwork peach & brown leaves. Though you sometimes see this as the cultivar ‘Mosaica’, the reddish-olive-brown shows up in varying degrees in a few forms of that species. ‘Haleakala’ has a completely brown leaf.

I love Cordyline ‘Red Star’, which is the centrepiece of this fabulous urn by the Toronto Botanical Garden’s gifted horticulturist Paul Zammit. Though it often looks more burgundy, here it reads as rich brown, especially with the matching heucheras.

Phormiums or New Zealand flax have been a big part of the tropical gardener’s arsenal, and many are bronze- or olive-brown. This is lovely ‘Dusky Chief’.

And where would gardeners be with annual sweet potato vine (Ipomoea batatas)? One of the richest is mocha-coloured ‘Sweet Caroline Bronze’, shown below with Pelargonium ‘Indian Dunes’.

There are countless cultivars of the annual foliage plant coleus (Plectranthus scutellarioides), and a few hit the brown jackpot, like ‘Velvet Mocha’ below.

Pineapple lily (Eucomis comosa) ‘Sparkling Burgundy’ has olive-brown foliage that really adds depth to a garden, like the Ladies’ Bed at the New York Botanical Garden.

Brown-flowered perennial plants are, admittedly, in short supply (many gardeners likely wondering why you’d even want a brown flower) but there are strange and lovely bearded irises that come in copper and cinnamon shades, like ‘Hot Spice’, below.

And we simply cannot leave a discussion of brown in the plant world without talking about the genus Carex.  Whether it’s Carex testacea, like this fun bronze-headed sculpture in Marietta & Ernie O’Byrne’s Northwest Garden Nursery in Eugene, Oregon……

northwest-garden-nursery-carex-testacea

….. or Carex buchananii in my very own sundeck pots a few years back.

carex-buchananii-in-pots

I loved the way the Toronto Botanical Garden’s Paul Zammit used Carex buchananii in this spectacular run of windowboxes, along with orange calibracoa, the golden grass Hakonechloa macra ‘All Gold’, golden cypress and kitchen herbs.

carex-buchananii-toronto-botanical-garden-planter

And, yes, C. buchananii can be counted on throughout the snows of winter. (Whether it reappears in spring depends on how cold winter got!)

BUT….. gardeners do not live by plants alone. There are furnishings! And they can be brown & beautiful, like these cool, dark-brown metallic planters at Chanticleer Garden, in Wayne PA.  (Check out the carex inside.)

Speaking of Chanticleer, I loved this rugged brown wood-and-COR-TEN steel bench and pergola in their Tennis Garden – and look how lovely brown furnishings are with brilliant chartreuse foliage.

chanticleer-tennis-garden-pergola-bench

Weathered COR-TEN steel is all the rage these days, being a stable, rusty finish that needs no upkeep. It was used to spectacular effect to make this canoe-like planter at New York’s High Line, holding interesting, moisture-loving plants flanking the garden’s water feature.

Water features are another way to bring a shot of brown into the garden. Have a look at the drilled ceramic urn fountain, below, which I photographed at Seaside Nursery in Carpinteria, California.

Let me finish up with a few sculptural details in shades of brown. Let’s start with whimsy – and a little Pythagorean creation from Suzann Partridge’s annual Artful Garden show.  Isn’t she sweet?

And then let’s move to elegance: a handsome, rusty obelisk perfectly placed within a flowery border at Northwest Garden Nursery in Eugene.

Finally, I’ll sign off with a little farewell to summer: a September bouquet filled with brown prairie seedheads and grasses, from my Lake Muskoka meadow to you. And a reminder to remember that brown is a colour too!
