A Denver Floral Extravaganza – The Garden of Rob Proctor and David Macke

What a treat I had back in June, along with more than 70 other garden bloggers during our annual “Garden Bloggers’ Fling”, to visit the beautiful garden of Rob Proctor and David Macke in the Highlands district of northwest Denver – and then to visit it again in softer light, the following morning! So in the midst of a very busy summer up here on Lake Muskoka (during which I’ve scarcely had a moment to revisit my photos) I nevertheless wanted to share images from my visit.  If you arrive in June, this is what greets you even before you open the charming front gate.

In front of the house is a “hellstrip” from heaven, below, filled with a drought-tolerant symphony of plants in purples and soft yellows. It’s your first clue that the plantings here have been designed by a master colourist who is also a painter and botanical illustrator. Rob now appears on Denver’s 9NEWS twice weekly as a garden expert, but at one time he was co-director with Angela Overy of the Denver Botanic Gardens School of Botanical Illustration.  He also served as the DBG’s Director of Horticulture from 1998 to 2003.  As his friend and former colleague, DBG Senior Curator and Director of Outreach Panayoti Kelaidis said in an interview once: “He transformed a sleepy, provincial research garden facility and made us one of the great display gardens in America.”

Bloody cranesbill (Geranium sanguineum) creates soft cushions of magenta blossoms in front of lavender-blue meadow sage (Salvia pratensis), middle left. At middle right is purple woodland sage (Salvia nemorosa).

Bees were everywhere, including this honey bee nectaring on the woodland sage.

Two unusual xeric plants are lilac-purple Kashmir sage (Phlomis cashmeriana) and golden drop (Onosma taurica), below.

At the eastern end of the hellstrip, a brighter colour scheme featured….

….. apricot desert mallow (Sphaeralcea ambigua) with basket-of-gold (Aurinia saxatilis).

A metallic green sweat bee (Agapostemon virescens) was nectaring on the desert mallow, while….

….. nearby,  showy milkweed (Asclepias speciosa) was awaiting monarch butterflies.

The word “hellstrip” is usually attributed to Colorado garden designer Lauren Springer Ogden, author of the acclaimed book The Undaunted Garden, among others. She and Rob also co-authored Passionate Gardening: Good Advice for Challenging Climates.  In an article she wrote for Horticulture magazine back in 2007, Ogden wrote of the Water Smart Garden she designed for Denver Botanic Gardens, shown in my photo below:  “The Denver Botanic Gardens’ former director of horticulture, Rob Proctor, played a crucial role in developing the full potential of the garden. The first couple of years it floundered—a good number of the called-for plants were not actually put in, and it fell under poorly trained and often careless maintenance. When Rob took over, he made it his priority to support the richness of the planting and the high level of care the garden deserved. He let me shop personally for many of the missing plants and add the beginnings of a collection of fiber plants that now brings so much to the dynamic year-round textures of the garden: nolinas, yuccas, agaves, and dasylirions—plants that just a few years ago were rarely used in Colorado gardens and often thought not to be hardy.

Though I could have spent an hour exploring the luscious hellstrip, I was ready to find what waited on the other side of the gate in the ebullient gardens that surround the 1905 “Denver square” brick house that Rob and David moved into in May 1993.

I was invited in to look at some of Rob’s art.  I loved this botanical rendering of a passionflower, one of many of his works hanging in the house.

But I was anxious to see what was out back, so I made my way past Stranger, the stray cat that hung around Rob and David’s garden for such a long time that he first got the nickname, then his new home.

Though Stranger elected to stay behind on the sunroom table, Mouse accompanied me out onto the brick-paved patio.

And what a patio it is, nestled into its own little garden spangled with lilac-purple Allium cristophii. Here we see the first wave of hundreds of containers that Rob and David fill with annuals each season, adding to pots containing tropicals, bulbs, succulents or perennials.  Pots with tender plants are lifted outdoors each spring, nurtured and watered all summer, then transported back to the basement in autumn before Denver’s Zone 5 winter winds blow. Cobalt blue – a favourite colour – is the unifying hue here.

Teak benches and comfy cushions abound here and throughout the garden.

Tropical foliage plants mix with colourful annuals and succulents like Sedum rupestre ‘Angelina’ pair with potted lilies. Incidentally, Rob is an expert in bulbs in pots, having written The Oudoor Potted Bulb: New Approaches to Container Gardening with Flowering Bulbs way back in 1993, the year they moved here.  It’s one of sixteen books he has authored or co-authored.

Though their property is more than a half-acre with several discrete garden areas, the patio is a lovely intimate extension of the house.

When I visited the first time, Rob, left, in his trademark vest and David, a retired geologist, right, held court out here.

I was impressed that David was able to reach out and pick a succulent pea….

….. from a pot of dwarf ‘Tom Thumb’ peas on the coffee table.

However on my second visit, it was just Mouse and me.

I enjoyed the sound of water from the raised goldfish pond….

….. and the splash of water from a unique watering can fountain set among pots on the stairs to the house.

But I was anxious to head out to explore the garden. When Rob and David moved in 26 years ago, the first thing they did was cut down eight “half-dead Siberian elms”.  Said Rob in a 1995 article for American Horticulturist, he wanted to build perennial borders. “Because of the relatively formal look of the late Victorian Italianate house, I chose a strong, geometric layout of long borders. Occasional half circles soften the straight lines. Within this framework, I indulge in the controlled chaos that we associate with traditional herbaceous borders.”  He carved out two rectangular beds each measuring 16 x 60 feet (4.9 x 18 metres) with an 8-foot wide strip of lawn in between. He then designed a backdrop of 12 brick columns – six per bed – connected by lattice screening and had a mason erect them on deep concrete footings.  That resulted in four 8 x 60 foot perennial beds, two of which are visible below. At the far end on the property’s south boundary line is the gazebo, built atop an old carriage house and featuring a winding staircase to the flat roof and a shady dining area within.  “Climbing the staircase,” wrote Rob, “it’s possible to view much of the garden from above.”

Mouse followed me dutifully out into the garden.

The colours here in June were exquisite, with purple and blue catmints, campanulas, cranesbills, meadowrues, salvias and veronicas enlivened by brilliant chartreuse. “Borders are like paintings,” said Rob. “Each one starts as a blank canvas. Working with a palette of plants, rather than paints, the possible combinations are limitless. The twin borders that cut through the middle of the garden contain the colors that I naturally gravitate towards – the blues, purples, and pinks.”

Each border held dozens of ideas for combinations. When I visited on June 17th, star-of-Persia onion (Allium cristophii) looked perfect with Kashmir sage (Phlomis cashmeriana)…..

….. and softened the flowers of broad-petaled cranesbill (Geranium platypetalum).

By the way, if you ever want to go down into a taxonomic rabbit hole, take a look at my blog on Allium cristophii.

The bold foliage of American cow parsnip (Heracleum maximum), below, offers a strong contrast to the soft colours and shapes of the central border.  Later in summer, the white flower umbels reach up to 8 feet (2.5 metres).  In one of the 2018 video clips from 9NEWS, Rob gives some pithy advice on how to handle this phototoxic native – just don’t!  Clambering over the lattice in the back of this photo is golden hops (Humulus lupulus ‘Aureus’), one of a number of vines that Rob encourages for its lovely effect. As he wrote:  “The golden hops vine needs little encouragement to thread through five or six feet of pink and blue flowers in this border, providing fresh, almost springlike foliage even in midsummer.”

Rob has used the red-leaved rose Rosa glauca as a background feature in one border, less for its single June flowers than for its strong foliage accent in order to enhance the massive beauty bush flowering in the background.

This was the view north along the twin central borders back to the house.

The third long border to the east featured white roses and the tall spires of Verbascum bombyciferum ‘Arctic Summer’….

…… nestled in a snowy cloud of sea kale (Crambe cordifolia).

The fourth long border on the west side is a confection of pinks and burgundies – peonies, roses and cranesbills in June. As it turns west near the immense beauty bush (Kolkwitzia amabilis), Rob gave special consideration to the unique colouration. “The beauty bush, its pale pink blossoms tinged with coral, inspired the color scheme of the surrounding plantings as the border turns to the west”. For the garden nearby, he chose sunset colours in lilies, red valerian, red sunroses, salmon pink nicotine and coral bells mixed with chartreuse and bronze foliage, to name a few.

In fact, he captured all three tints of beauty bush flowers in the cushions on the chairs placed strategically under its flowery boughs. This is colour perfectionism!  Because of its size, Rob estimates the shrub was planted fairly soon after it was introduced to the west via Ernest “China” Wilson, who sent seed to Veitch’s Nursery in England in 1901. Flowers did not appear on the first seedlings for nine more years.  It became very popular in gardens in the mid-20th century but deserves to be planted in gardens where its size can be contained.

This view melted my heart.  And there were bees in that pink rose… scroll down to the video at the end of my blog and you’ll see them.

Clematis recta is a superb June-blooming herbaceous clematis.  I’m not sure how Rob manages to keep his upright, but it does benefit from some kind of support, like a peony ring.

Further along, near the nuts-and-bolts of the garden (compost bins, potting shed, etc.) I noted one of Rob’s favourite strategies to introduce a splash of colour into the borders: a well-positioned pot with a bright red annual coleus.  He does the same thing with red orach (Atriplex hotensis ‘Rubra’).  Later there will be larkspur here.

We’ve arrived at the back where the gazebo is sited on the foundation of an old carriage house.  A spiral staircase climbs to the top; it must be a lovely spot to sip a glass of wine and look back on the borders.

Down below, there was a table and chairs under the roof, providing a nice view and much needed shade in Denver’s notoriously hot summers.

Luscious tuberous begonias thrive here.

What a great spot for al fresco dinners – surrounded by tropicals and foliage plants. I loved the louvered panels at the back.  And what do you suppose lies behind that dark picket fence?

Well, it’s an alley. A place where most gardeners would be content to create a couple of parking spots and leave it at that. But not David and Rob…. all that sunshine!  So they not only reserved places to park their cars, but….

… also designed a potager divided into eight Native-American-inspired “waffle” beds, which are dug down below grade to capture precious rainwater, just as waffles collect syrup.

Bordered in thyme, the beds contain different types of seed-grown vegetables.  At the centre of the potager is an artful cluster of pots.

As with every part of Rob and David’s garden, there is a comfy, colour-coordinated place to sit and relax – even in the alley!

Biennial clary sage (Salvia sclarea) is one of many plants allowed to self-seed here.

I loved this succulent-filled strawberry jar in the midst of the vegetables.

I headed back into the garden and made my way down the east side, where an old driveway has been re-imagined as the “gravel allée”.  It’s a series of tableaux: sitting areas with colour-matched accessories and plants.  Periwinkle blue and rusty-orange… sigh. You can imagine how enchanting this is for someone who called her blog “thepaintboxgarden”!

Such an inviting scene……

Double clematis are often less hardy than small-flowered species and varieties, so Rob pots them up and takes them to a less exposed area for winter.

Speaking of CLEM-a-tis, I liked hearing Rob educate his news colleagues on proper pronunciation of the vine.

Mouse was getting a little impatient for me to leave, so led me down the gravel path….

…. to containers nestled around a birdbath. Have you been counting the pots? I understand there are more than 600!

I’m a big fan of red-with-green in planting design  and this section of the path tickled my fancy.

Under the mature trees here was another semi-shaded sitting area set in amongst shrub roses with yet another bench.  I loved the row of potted aloes!

Now I was gazing at the house through a delightful thyme parterre herb garden.

I walked around to the south to see the view….

…. and then from the corner nearest the house. This is such a classic design – also created in the lowered waffle bed manner – and so lovely when the thyme…..

…. and the rose are in flower together.

I had a plane to catch later that afternoon, so gathered up my things and headed around the house to the front. There on the west side under the shade of the trees was one final treasure in Rob and David’s garden. It was a patio filled with shade-loving plants adjoining their sunken garden (down the stairs and just out of the photo below).   As Rob wrote in 1995: “One weekend, while digging up self-sown tree-of-heaven saplings, we kept hitting brick. We determined that it was the foundation to a building, about 15 by 10 feet. Friends joined us for some urban archeology as we excavated it, finding hundreds of patent medicine bottles, broken china, and a waffle iron designed for the top of a wood stove. The foundation may have supported a summer kitchen or an earlier house, perhaps a farmer’s. We stopped digging at about four feet and, exhausted, decided our sunken garden was deep enough. We mixed in extra-rich compost to nurture the shade-lovers we intended to plant there.”

It was so hot that day in June, I would have loved to settle in the shade on those blue and red cushions and contemplate the lovely caladium. But it was time to go.

So, reluctantly, out I went through the gate entwined with Virginia creeper, to meet my ride.

As a bonus, I created a little musical tour through David and Rob’s enchanting garden, co-starring a selection of the bees that find nectar there:

Rob and David have shared their garden annually for many years now. It’s for a cause near and dear to them – and to Stranger and Mouse, too. And I’m so glad I was able to share their garden with you, too.

Black for Garden Drama

Late August brings us into the dog days of summer, and there’s nothing that cures a dog day like a dose of drama. That’s why I reserved this month for BLACK! (And thanks to a little summer travel, I’m just getting in under the August wire.)

Black flowers & leaves-The Paintbox Garden

Of course, no plant leaf or flower is completely black. Inspected closely, there is always green (for photosynthesis) or dark red, purple or deep bronze underlying the apparent dark floral pigments. But there’s a rich roster of plants that can be called upon to inject a little black magic into the garden, whether it’s with dark-as-night foliage or betwitchingly black blossoms. And for my money, no one offers up the design potential of black like Vancouver’s Van Dusen Botanical Garden. Here’s their black and gold border, with barberries, colocasias, sedums, eucomis and black mondo grass, to name just a few. Isn’t it lovely?  And doesn’t that dark foliage look spectacular paired with chartreuse?

Black Border-Van Dusen Gardens

Here’s a closer look at a portion of Van Dusen’s wonderful border, with a black taro, ‘Black Tropicanna’ (or perhaps ‘Australia) canna and ‘Brunette’ snakeroot (Actaea racemosa ‘Brunette’).

VDG-Black-&-Chartreusejpg

Mondo grass (Ophiopogon planiscapus ‘Nigrescens’) is one of the darkest ‘black’ leafed plants, and one of the most dramatic for pairing with bright colours.  I love the way Victoria’s Horticulture Centre of the Pacific uses it in combination with Sedum ruprestre ‘Angelina’, seen below in spring when it’s still gold.

HCP-Ophiopogon 'Nigrescens' & Sedum 'Angelina'

Here’s how it looks at HCP with golden oregano (Origanum vulgare ‘Aureum’).

HCP-Ophiopogon & Origanum vulgare 'Aureum'

At gorgeous Chanticleer Gardens in Wayne, Pennsylvania, the Japanese Garden employs Japanese black mondo grass as a dark edging under bamboo ‘fencing’.

Chanticleer-Ophiopogon & Aruncus-Asian Woods

Other dark, grass-like plants include fountain grass, particularly Pennisetum ‘Princess Caroline’ and ‘Vertigo’, below, shown with orange zinnias at New York’s Conservatory Garden in Central Park.

Conservatory Garden-Zinnia & Pennisetum 'Vertigo'

And here is Pennisetum ‘Princess Caroline’ doubling down on black with the ornamental pepper Capsicum annuum ‘Black Pearl’, a fabulous black annual.

Capsicum 'Black Pearl' & Pennisetum 'Princess Caroline'

Black and red look spectacular together, too, as demonstrated by Capsicum annuum ‘Black Pearl’ paired with annual red Salvia splendens.

Capsicum 'Black Pearl' & Salvia2

The best spring bulb for injecting a little early-season black is Tulipa ‘Queen of Night’. I love this one, and use it liberally in my own spring garden. Here it is at Toronto’s Casa Loma bringing depth to citrus colours….

Tulipa ''Queen of Night' & yelllow-orange tulips

…. and at Toronto’s Spadina House as a pretty partner to pink….

Tulipa 'Queen of Night' & 'Black Diamond'

…. and echoing the dark foliage of ‘Diabolo’ ninebark (Physocarpus opulifolius) at the Toronto Botanical Garden.

Sambucus & Tulipa 'Queen of Night'

Shortly after the tulip season comes columbine season, and there’s nothing more dramatic than a black, pleated form of Aquilegia vulgaris.

Aquilegia vulgaris 'Black Barlow'2

One of my favourite dark-leafed shrubs is Black Lace elderberry (Sambucus nigra ‘Eva’), seen below with a pink Phlox paniculata at Northwest Garden Nursery in Eugene, Oregon.

Northwest Nursery-Eugene-Sambucus&Phlox

For some reason, annual sweet potato vine (Ipomoea batatas) lends itself genetically to black colouration. Here is ‘Ace of Spades’ with yellow rieger begonias in Toronto gardener Shari Ezyk’s lovely urn.

And adding a dark carpet to sea oats (Chasmanthium latifolium) at the Conservatory Garden, in New York.

This is the fancy-leafed ‘Blackie’, with ‘Lemon Gem’ marigolds at Toronto Botanical.

Ipomoea & Tagetes

Another species that has benefited ‘darkly’ from plant breeding is tropical taro or elephant ears (Colocasia esculenta). Here we see the big leaves of  ‘Royal Hawaiian Black Coral’ exploding with a canna lily out of a sea of chartreuse foliage at Montreal Botanical Garden.

Montreal Botanical-Colocasia esculenta 'Royal Hawaiian Black Coral'

Black taros are also used beautifully with other tropicals at Nancy Goodwin’s Montrose Garden in Hillsborough, North Carolina.

Montrose-Black Taro1

There are some good black petunias, including yellow-striped ‘Phantom’.

Petunia 'Black Velvet'

Sometimes we forget that seedheads can have visual impact in a late-season garden, especially when they’re as dark as Rudbeckia maxima, shown in front of Calamagrostis acutiflora at Wave Hill in the Bronx.

Black Seedheads-Rudbeckia maxima

Purple coneflower has dark seedheads, too. Here it is behind the golden fall foliage of Amsonia tabernaemontana in autumn.

Black Seedheads-Echinacea & Amsonia

And don’t forget the zingy seedhead possibilities of blackeyed susans!

Black Seedheads-Rudbeckia 'Goldsturm'

We can also add black with furnishings, of course. Here’s a modern black steel fence I fell in love with at the Corning Museum of Glass in upstate New York.

Black Garden Fence-Corning Museum of Glass

And this black-stained garden arch is the height of design sophistication (as are black fences).

Black Garden Arch

Black chairs? What about using some black stain and artistic flourish to turn a Muskoka (Adirondack) chair into a work of art, as my artist son Jon Davis did for me many years ago.

Chairs-Muskoka-Adirondack Style

Even a simple black bistro chair can up the dark drama quotient, especially if it’s in renowned garden guru Tom Hobb’s former Vancouver garden.

Chair-Tom Hobbs

In the black accessories department, you can’t go wrong with a simple black obelisk, especially when it chums with a pink daylily.

Black Iron Obelisk

Moving to containers, black adds a dollop of sophistication via this beautiful trio of planters at Toronto Botanical Garden. No other colour would work as well with the flamenco-red flowers and foliage, all designed by horticulturist Paul Zammit.

Toronto Botanical Gardes-Cordyline-Acalypha-Geranium-Ipomoea

I’ve written about Paul’s creative container designs before, but he does have a special skill for knowing just what to use, like these kitchen herbs (parsley, sage), grasses (carex, hakonechloa) and orange calibrachoas in a run of basic black iron window boxes.

Toronto Botanical Garden- Containers

I’ll finish my contemplation of black in the garden with containers from my favourite public garden, Chanticleer. Here’s a lovely black urn that repeats the black-red theme of some of the photos above, with red calibrachoa. Stunning, isn’t it?

Pot-Chanticleer-Callibrachoa 'Alpha Kona Dark Red' & Melilanthus major (1)

And finally, a half-dozen statuesque black planters that are as much about defining space in this Chanticleer garden, as they are containing plants.

August in New York’s Conservatory Garden

It was a steaming hot August afternoon in New York City. I’d arrived just hours before from Toronto with three days of area garden viewing and photography on my agenda. I hadn’t made plans for today, but then I remembered a city garden I hadn’t visited for more than a decade. There were still hours of daylight, albeit crushingly humid hours with temperatures in the mid-90s. So I filled my water bottle, slung my camera bag over my shoulder and headed out of my hotel (Hotel Boutique at Grand Central), conveniently located near Grand Central Station and the 42nd Street Subway. The subway tunnel felt like a tropical jungle, but it was nothing compared to the inside of the subway car heading north, whose air-conditioning was broken. “59-68-77-86”, I counted down the stations, fanning myself madly and hoping I wouldn’t faint before arriving at my stop.  When I climbed the stairs to 96th Street (the dividing line between Manhattan’s Upper East Side to the south and Spanish Harlem to the north), the humidity was even higher. I’d only walked a block or two westward towards Central Park before the first fat raindrops fell. Fortunately, I’d tucked my umbrella into my bag and as the rain became a torrent, I pulled my camera bag closer to me and hurried on. By the time I’d crossed Fifth Avenue and walked north along the park to 105th, people were running out and taking shelter under trees or dashing along the sidewalk to their cars or buses. I, on the other hand, was heading into the park, and as I entered the Conservatory Garden through the Vanderbilt Gate, the rain magically abated and the lawns and hedges steamed in the late day heat. Ahead of me was the formal Italianate garden with its lush lawn and fountain.  In May, those crabapple trees on the sides are fluffy clouds of pink and the pergola in the distance is wreathed in wisteria.

Italianate Garden-Conservatory Garden-New York

I watched a young girl playing in the fountain’s cooling spray.

Fountain-Conservatory Garden-New York

The Italianate garden is in the middle, one of three sections that make up the 6-acre Conservatory Garden, which is named for the lavish greenhouse that occupied the site from 1899 to 1934, before it was officially opened as a garden in 1937. After the second world war, the garden was increasingly neglected; by the 1970s it was a derelict place  Under Central Park Administrator Elizabeth Barlow Rogers and renowned New York designer and public gardens champion Lynden Miller (who also did Bryant Park and numerous other urban spaces), the gardens were completely renovated and reopened in 1987.

At the north end is the French garden….

… and the Untermyer Fountain, “Three Dancing Maidens”, a 1947 donation to Central Park from the children of famed New York lawyer Samuel Untermyer, whose Yonkers estate is now a conservancy open to the public.

Untermyer Fountain-Conservatory Garden

But as a plant-lover, I was interested in revisiting the southernmost section, the English Garden. To get there I walked past the perimeter of the French garden, with its crabapple allées. A few visitors took shelter from the last raindrops under their umbrella.

Rainy Allee-Conservatory Garden

I passed a raised garden filled with a tapestry-like assortment of luscious tropicals.

Tropical plants-Conservatory Garden

Then I was walking into the English Garden under a magnificent sourwood tree (Oxydendrum arboreum), its tiny, pendulous, white blossoms alive with bumble bees. Trees, shrubs and various perennials act as leafy enclosure in the outer beds in the concentric arrangement of hedge-backed plantings in Lynden Miller’s original design. The current curator of the English garden is Diane Schaub, whose talent is very much on display here. (See note at bottom of my blog).

Conservatory garden-Sourwood tree

Below is one of Lynden Miller’s favourite shrubs: oak-leaf hydrangea (Hydrangea quercifolia), as the big panicles take on their tawny autumn hues.

Conservatory Garden-Oakleaf Hydrangea

The outer bed below features Japanese anemones (Anemone x hybrida), an August mainstay, with cascading Japanese forest grass (Hakonechloa macra ‘Aureola’) in the foreground.  Mid-border is another Lynden Miller trademark: a clipped purple barberry globe (Berberis thunbergii), adding a sculpted architectural note.  (One of my favourite photos from a visit here in the 1990s was one of these globes graced with deep-violet Clematis durandii.)

Conservatory Garden-Borders1

Here is a closeup of Japanese anemone with the delicate flowers of Thalictrum rochebrunianum.

Conservatory Garden-Thalictrum & Anemone

White coneflowers (Echinacea) brighten the shade-dappled outer bed under the trees. There’s a lovely colour echo of the cones with the dark foliage of the black bugbane beside it (Actaea racemosa Atropurpurea Group).

Conservatory Garden-Echinacea & Hostas

Post-rain, the subtle baby-powder fragrance of summer phlox (Phlox paniculata) and  the perfume of hosta flowers wafted in the enclosed spaces in the garden.

Conservatory Garden-Phlox & Hosta

But as lovely as the mixed perennial-shrub beds were in the outer rings, it was the inner hedged beds in the English Garden that beckoned me. They offered a master class in the use of annuals and tropicals to create exquisite designs that can be changed every year.  But these aren’t your grandma’s annuals; there are no impatiens, geraniums or petunias in the garden. Instead, you see statuesque plants in lovely colour combinations that rival any perennial border. The bed below offered fabulous ideas for combining chartreuse foliage with oranges and bronzes.

Conservatory Garden-Red flowers

Here’s a closer look at the inspired pairing of Cuphea ‘David Verity’ — one of many ‘zing’ plants — with a charteuse colocasia.

Who could dislike stiff, old canna lilies when they do THIS in the late afternoon sun? (Especially when paired with bronze fennel flowers and a luscious azure-blue Salvia guaranitica.)

Deep burgundy-blacks — like Dahlia ‘Mystic Illusion’, front, and the grass Pennisetum ‘Vertigo’, below —  added depth to a dark-foliage border.

Exploring all the inner beds was a challenge. Just when I thought I’d seen them all, I’d turn a corner and spot something entirely new!  I loved the way this heuchera (maybe ‘Black Taffeta’?) anchored the design below.

In some hands, pink flowers can be just too cotton-candy sweet. But Diane Schaub used a deft touch, below, to incorporate the pink spires of Agastache cana ‘Heather Queen’ and the zingy pom-poms of Gomphrena ‘Fireworks’ and purple Verbena bonariensis into a pale-green matrix of tropical plants, including variegated Furcraea foetida ‘Mediopicta’, centre, and variegated plectranthus (P. forsteri ‘Green on Green’), right.

Stronger pinks like the verbena, below, were partnered with darker greens, like Colocasia esculenta ‘Blue Hawaii’.

I loved the combination, below, of Gomphrena ‘Fireworks’ and blue pitcher sage (Salvia azurea). Such good clear colours.

Gomphrena 'Fireworks' & Salvia azurea

Sometimes horns would honk nearby and I would be reminded that I was in a leafy enclave a stone’s throw from one of the most famous streets in the world: Fifth Avenue!

Unusual annual pairings were everywhere. Below is Perilla frutescens with airy Ammi majus.

And I adored this vignette of magenta-pink Gomphrena ‘Fireworks’ with lacy centaurea, a deep-red salvia and coleus.

I was very impressed with the way tropical shrub Tibouchina urvilleana, below, was used in the purple border. It looked perfectly at home with magenta Gomphrena globosa and dark pink zinnias.

Finally, that concentric maze of flowery beds led me to the intimate centre of the English Garden, with its enclosing borders and a pink-flowered crepe myrtle (Lagerstromeia indica). Benches were arranged so visitors could…….

I paused for a moment in the secret garden, but towering storm clouds were building in the sky to the west and it was time to head back to my hotel.

I bade farewell to this lovely secret garden and strolled out to catch a southbound bus to midtown. What a lovely first evening for my short New York stay.
