Shrub rose ‘Alexandra, Princesse de Luxembourg’
During July in the Peggy Rockefeller Rose Garden, you’ll find the gardeners and volunteers bent over headfirst into the rose beds filling buckets with faded blooms. We’re deadheading, or as they say in England, “refreshing” the rose shrubs. Deadheading is summer pruning and very easy to do. Simply cut the stem bearing the faded rose to a point where a set of healthy leaves is attached. This is a time-consuming job that will reward you with beautiful new roses in a few weeks time.
There are still plenty of roses to enjoy in the garden. The sweetly scented ‘Alexandra, Princesse de Luxembourg’, a blush-pink shrub rose, and ‘David Rockefeller’s Golden Sparrow’ are both in full bloom. Last week, in Paris, this yellow beauty won the prestigious Gold Medal for Landscape Roses at the International Rose Trials of Bagatelle.

As spring has turned to summer, so my attention has turned to the Native Plant Garden meadow. It changes daily now, with new plants offering their voices to the swelling chorus. One of my very favorites is Bush’s poppymallow, Callirhoe bushii. Set among fine grasses, golden tickseed, and brilliant white wild quinine, its white-eyed magenta cups demand attention.
Happy in average or dry soil, Bush’s poppymallow loves a sunny site and will flower throughout the summer and sporadically into the early fall. In our meadow, its loosely sprawling stems pop up through its neighbors, creating lovely and spontaneous living bouquets. It has seeded itself around gently, but editing is easy if you wish. All Callirhoe have taproots which makes them very drought tolerant, but also very difficult to move once established.

The flowers of Penstemon cobaea var. purpurea are much larger than those of the other beard-tongues in the Native Plant Garden.
I am batty for beard-tongues. No, I don’t mean the furry-mouthed feeling that people with actual social lives get after long nights of too many cocktails, I mean the more than 250 species of Penstemon, a genus of perennials and biennials native to North America from the Maine woods to the alpine meadows of Idaho and the deserts of California. With tall clusters of flowers as beautiful as their common name is ugly (the moniker beard-tongue refers to tufts of hair that emerge from the sterile fifth stamen of certain species), beard-tongues carry late spring in the Native Plant Garden.
The most common beard-tongue in cultivation is Penstemon digitalis ‘Husker Red’, selected in 1983 by Dr. Dale Lindgren of the University of Nebraska for its maroon leaves, long-lasting inflorescences of white flowers, and extreme hardiness (it thrives in Nebraska!). We planted ‘Husker Red’ in the Native Border, where its flowers bridge the gap between the peaks of mid-spring and mid-summer bloom, and its foliage adds a dash of welcome color throughout the growing season.

Stewartia rostrata
Ever since my journey into the world of plant obsession began, one my favorite times of the year has always been what I affectionately call “Stewartia season.” This delightful stretch always reminds me of summers spent immersed in unique plant collections, but always being drawn back to this one fascinating group of plants.
The genus Stewartia contains a handful of large shrub and tree species native to eastern Asia and two indigenous to the southeastern United States. Stewartia species all have beautiful white flowers with an obvious tuft of anthers in their center. Their floral show takes place in early to mid-summer, but many species also put on a fantastic display of orange to crimson fall foliage, extending the plants’ season of interest.

Allium giganteum
When choosing a new plant to add to a garden, some people choose plants for beauty. Others choose plants with a purpose, for example a shade tree or an upright evergreen for structure in the garden. Well, isn’t it nice to find a plant that fills more than one need?
One such plant is the ornamental allium. If that name sounds familiar, it should. There are many species and cultivars of the genus Allium, which include the well-known chives, onions, and garlic.
The flower appears to be a single, spherical flower borne on single upright stems. However, the globes are actually made up of many small, star-shaped flowers radiating out from the center. Alliums come in many sizes. The flower heads range from tiny to quite large, and the density of the flowers can be quite full, creating a dense flower head; or very open, making for an airy flower head. The stems also range from a short 12” to an astounding 36”. Colors can range from dark purple to the light pink, with some white cultivars. The different species and cultivars can be massed in large numbers or mixed all together for varying effects in the garden.

Frost-killed hydrangea stems should be pruned back to live wood.
On April 16 at 6 a.m., the Garden’s weather station reported a low temperature of 30.2°F. The freezing temperatures were accompanied by about a half inch of icy slush that coated the greening turf and accumulated in the chalices formed by the opening flowers of saucer magnolias, which had just emerged after a string of warm April days that, I hoped, signaled the end of our seemingly interminable winter. Needless to say, the Garden’s venerable saucer magnolias did not have their best spring.
For many, memories of that hard April frost will be erased by this week’s temperatures—approaching 90°F as I write—and the reappearance of seersucker suits in midtown. Those of us who love plants will be reminded of April 16 every time we see an old-fashioned Hydrangea macrophylla over the next few months. With the exception of remontant (re-blooming) varieties such as Endless Summer® (more on these later), Hydrangea macrophylla flower from buds formed during the previous growing season. Dormant through the long winter, these buds began to swell as temperatures finally rose in early April, only to be zapped by the hard mid-April frost.

Himalayan fox tail lily (Eremerus himalaicus)
One of my favorite plants on our new Seasonal Walk so far is the Himalayan fox tail lily, Eremerus himalaicus. Re-designed by renowned designer Piet Oudolf and planted late last fall, it has been a thrill to watch the garden unfold. After a very cold winter filled with lots of nail-biting, the plants have emerged healthy, happy, and simply glorious. As all the best gardens do, this one changes magically from week to week. The leading characters now are our native columbine Aquilegia canadensis (complete with hummingbirds darting around enjoying the red and yellow flowers) and the magical Himalayan fox tail lily. Elegant spires of white star-shaped flowers dance gracefully down the length of the double border. They are four feet tall this year, but hold the promise of more height in years to come as they settle in.
Fox tail lilies are easy to plant. Their tubers look much like a sea star with a whole mess of legs wearing a dunce cap. Dig a hole wide enough to spread out their roots but not too deep—their noses should be just a few inches underground. They don’t enjoy wet soil and love the sun.
The Seasonal Walk is only just beginning to seduce with its tapestry of plants. I love the fox tail lilies now, but I’m sure there is something else that will start blooming next month that will steal my fickle heart.

Wild columbine (Aquilegia canadensis)
Asking a curator to pick a favorite plant is akin to asking a parent to tell you their favorite child—surely an impossible choice. Nevertheless, there are moments when, with plants and children alike, they do something that gladdens the heart and captures otherwise divided affections.
Such a moment is upon us in the Native Plant Garden. A visit this week will reward with the sight of spectacular drifts of the native wild columbine (Aquilegia canadensis). Their delightfully fine-textured, almost fern-like foliage is a perfect backdrop to the sprays of delicate, red-spurred flowers, with just a light flush of yellow on the petals and a cluster of exerted yellow stamens. A not insignificant bonus is that they are pollinated by Ruby-throated Hummingbirds, and this generous display is sure to offer a welcome sight to any migrating birds that make their way through the garden.

The moon gate in the Abby Aldrich Rockefeller Garden
The Free Dictionary defines “evocation” as the creation anew through the power of the memory or imagination. In the exhibitions department at The New York Botanical Garden we craft exhibitions years in advance with the intent of bringing to life distant lands, famous people, interesting plants, rarely seen gardens, and fantastical landscapes. Creating evocations is our job, and one that we take great pride in doing.
Not only do we bring the visual (garden composition) to the visitor, we also bring content to enrich their experience—including catalogs, signage, audio tours, plant tours, iPhone apps, related poetry tours, and programming. Our goals are to transport you, to immerse you, to educate you, and maybe, just for a moment, to help you forget about your life outside the Garden gates. Using our upcoming exhibition as an example, Groundbreakers: Great American Gardens and The Women Who Designed Them, I’d like to show you some of the behind the scenes of how we put together the exhibitions.
Starting with an exhibition idea, we begin to plot the idea on our calendar and determine which exhibitions will come before and after it. Initial themes are developed and concepts for the designs are discussed. Early in the process, a scouting mission is planned, so that any physical locations relating to the topic can be photographed and documented. Later, visits to libraries and archives are planned so that assets for the galleries and related collateral can be gathered.

It’s daffodil time! That dreamy, delicious time of year when even the greyest day is made brilliant by masses of cheerful blooms.
I’m often asked which is my favorite daffodil. It’s like asking me which of my children I love the most! I adore the slightly green, buttery yellow trumpet ‘Pistachio’ who is so handsome next to lavender pansies. But then ‘Surfside’ just blooms so enthusiastically with her swept back white petals and her frilled cup that fades to cream. How could I not pick her? And of course ‘St. Keverne’ is marvelous too. His rich golden yellow blossoms stand tall and strong and he perennializes so fabulously!
If you have a garden, really any kind of a garden except for a very wet site, and you don’t have any daffodils in it, plant some this fall! Simply plant them 3 times as deep as the bulb is tall with the root end down. If you aren’t sure which is the root end, plant them on their side and they will find their way! When choosing a variety, look for those that are described as being good perennializers. Daffodils will perform their best in full sun in well-drained soil, but they are very forgiving. We have swathes of daffodils planted in lawns here which make such marvelous spring scenes, but you have to be sure to leave their foliage up for at least 6 weeks before you mow.
Of course, the very best way to choose what to plant in the fall is to come see them in person this spring. Our grounds are now a living catalog, so come find your favorites!
