  • Coastal Garden in the Hamptons: Hollander Design’s Tips for a Deer-Resistant Beachside Landscape

    It’s not every day that a client asks their landscape designer to come look at a barge they’re thinking of buying, but that was exactly the call the team at Hollander Design Landscape Architects received a few years back. The property in question was a house that had been built on a torpedo barge in the 1950s and docked on a harbor in the Hamptons ever since. The bulkhead was in need of a total rebuild—and the landscape would need restoration afterwards. Hollander Design was up for the challenge.

    The clients ended up buying the house, and after a marine construction contractor rebuilt the bulkhead, walks, and the docks, Hollander Design returned to conduct major revegetation efforts. The clients were looking for a low-maintenance landscape, as they wanted the home to be a retreat from their busy, working lives. They desired a beautiful landscape, but they didn’t want a garden that would compete with the breathtaking setting. The trick would be to create the illusion that the barge and bulkhead were knitted into the marsh around them.

    “Everything that’s around the house is very wet and boggy, but their property happens to be a high, dry spot because it’s up on that bulkhead,” explains landscape designer Melissa Reavis, the director of Hollander Design’s residential studio. “So we chose plants that were appropriate to that area but completely different from the immediate area that it sits in.” Think beach grass instead of the nearby rushes, plus, beach plums and northern bayberry that are found in nearby dunes.

    In addition to its unique barge setting, the property experiences intense deer pressure (a challenge that many gardeners can relate to). Furthermore, the site is exposed to sea salt and increasingly frequent storm surges. “We were left with a pretty limited palette,” says Reavis, but she focussed on what she calls “bulletproof plants for a coastal environment” to create a garden that is almost as magical as its setting. Here, her formula for getting it right.

    The soil comes first.

    After the bulkhead rebuild, Hollander Design needed to replace a lot of the soil, which Reavis explains had been backfilled with whatever was on hand back in the 1950s. The new soil is mostly clean-draining sand, so that nutrients won’t leach into the water. “Everything that was replanted in that area is planted almost into direct sand and we don’t add any additional nutrient loads to the soil, to ensure that we weren’t affecting water quality around it,” Reavis explains.

    Design for minimal maintenance.

    To fulfill the owners desire for a low-maintenance landscape, Reavis eschewed turf lawn and instead planted native and climate-adapted perennials. Hollander Design’s maintenance team does a hard cutback in May to keep the plants from outgrowing their homes, which also ensures a long bloom, but otherwise the maintenance is minimal—and free of pesticides, herbicides, and fertilizers.

    Mimic the nearby aesthetic.

    “You feel completely enveloped by the harbor here,” says Reavis. “The landscape’s job here is just to make it feel as knitted into this magical world as possible.” To complement the landscape, Reavis pulled in not only native plants, but also climate-adapted ones that feel like they’re in the same world as the natural landscape beyond. “They’re all flowing grasses and flowing perennials, and so nothing feels out of place with the more native natural habitat,” says Reavis.

    Mints for the win.

  • Native Vines: Experts Share Their Favorite Native Climbers

    Native Vines: Experts Share Their Favorite Native Climbers

    Vines can hide an ugly fence or add beauty to trellis or doorways. When grown over an arbor or pergola, they can create shade. But when gardeners think of vines, the first thing that comes to mind may be imported ones like Japanese and Chinese wisteria, English Ivy, or the dreaded oriental bittersweet, which can all be difficult to get rid of (and have notoriously escaped our gardens and aggressively displaced native plants in the wild). There are many native vines, though, that can play a useful part in your garden scheme.

    Christina Koether, a backyard flower farmer, florist, and garden designer behind Nomadica in Weston, Connecticut, notes that tastes and awareness are gradually shifting: In October, for example, it will be illegal to sell both Japanese wisteria (Wisteria floribunda) and Chinese wisteria (Wisteria sinensis) in Connecticut. As a result, she says, “I think we will see native vines like Aristolochia macrophylla and Lonicera sempervirens become more popular again.”

    Here are 11 native vines that garden professionals are using in their designs:

    Dutchman’s Pipe (or Pipevine)

    Looking for a native vine to cover an ugly deer fence on the woodland edge of her property, Koether decided to try planting a pipevine (Aristolochia macrophylla), whose heart-shaped leaves were a favorite in Victorian gardens until favor shifted toward the imported Chinese and Japanese wisterias for their showier flowers. “Pipevine—it’s one of my favorite native vines,” says Koether, who admits that technically, it’s native to areas slightly further south than Connecticut, where she gardens. “But I rolled the dice when I bought them, knowing the butterfly that relies on it would likely start coming further north as temperatures increase each year.” Sure enough, this year, Koether watched pipevine swallowtail butterflies lay eggs on the vine, which hatched into caterpillars. In addition to being the host plant for the pipevine swallowtails, who rely on this plant to survive, Koether appreciates the playful pipe-shaped flowers in the springtime. 

    California Pipevine

    Out on the west coast, Andrea Hurd, the founder of Mariposa Gardening & Design Cooperative in Oakland, California, points to the California native pipevine (Aristolochia californica), which has larger, distinctive purple-striped, pipe-shaped flowers. “We have a garden where it has gotten well-established,” she says. According to the California Native Plant Society, this plant is common in moist woods and along streams in northern and central California. Like its cousin Aristolochia macrophylla, it is the host plant for the pipevine swallowtail, and there are other regional Aristolochia to explore, depending on where you garden.

    Coral Honeysuckle

    Not to be confused with Japanese honeysuckle (Lonicera japonica), which is considered invasive in most states, coral honeysuckle (Lonicera sempervirens) is native to the southeast and grows as far north as Maine and inland to the midwest—and is a favorite of several garden pros. Gena Wirth, a landscape architect and partner at SCAPE’s New York office, recently moved into a home in Brooklyn with a large fence that backs onto a subway corridor, on which she is experimenting with a number of native vines, including coral honeysuckle. “Lonicera sempervirens is such an easy-to-grow, adaptable plant that thrives in full and part sun environments,” says Wirth. “I love planting it in arches and garden windows, as its flowers reach for the light.” Koether notes that she also likes to use cuttings of both the greens and the flowers in her floristry work.

    Trumpet Vine

    If you want to attract hummingbirds, look to trumpet vine (Campis radicans) and its orange, trumpet-shade flowers. It’s native to eastern North America, as far north as Ohio and South Dakota. Fast- and high-growing, trumpet vine has a reputation for being aggressive (great if you want it to screen a fence), but the experts from the Brooklyn Botanic Garden, in their guide Great Natives for Tough Places, say that it can be controlled with pruning if you want to contain its vigor.

  • Yellow Jessamine: A Species of Gelsemium That’s a Very Toxic Plant

    Yellow Jessamine: A Species of Gelsemium That’s a Very Toxic Plant

    What native flowering vine is perfumed, profuse, and in bloom in early spring just when we need floral encouragement the most? It’s yellow jessamine, or Carolina jasmine—Gelsemium sempervirens. (Its species name—“always living”—refers to Gelsemium’s glossy, evergreen foliage.) This is a cascading, fast-growing vine that makes a spectacular bower over doorways, softening hard fence edges, and stopping passersby, even in their preoccupied, city tracks. It is also one of the most toxic plants on the planet.

    But don’t panic. Unless you’re a Russian whistleblower.

    Above: Yellow jessamine might be the ultimate curb appeal.

    Growing natively from Guatemala through Virginia, yellow jessamine’s first stop in the US is Texas, where it is often the first flower to bloom in the new year. It is widely distributed in the Southern US but also in the nursery trade, which has spread it beyond its natural range. It shows remarkable cold hardiness for a plant also at home in Central America. (There are three Gelsemium species: the others are G. rankinii, native to Southeastern US, and which has no scent; and G. elegans, native to East and Southeast Asia.)

    Above: Packed clusters of flowers are heavily scented.

    While European honeybees are drawn to the nectar-rich flowers of Gelsemium, especially if there is no other food source, the nectar in high doses may be toxic to them. At least, this is the chatter in concerned bee-keeping circles, but it is hard to find a study that confirms this—because there is no such study. Still, with ancient, anecdotal stories circulating via cut-and-paste (and cemented into truth by an entry on Wikipedia with a cul-de-sac of a citation), they are hard to dismiss completely.

    But what about native pollinators and yellow jessamine?

    Above: A bumblebee visiting a flower.

    Yellow jessamine might actively benefit native bumble bees: A 2010 study concluded that “gelsemine, a nectar alkaloid found in Gelsemium sempervirens, lessens the severity of gut pathogen infections in bumble bees.” Self-medicating bees. I have seen fat carpenter bees besieging yellow jessamine, and “robbing” the flowers by puncturing the base of their nectaries from the outside, to suck out sweetness, leaving less food for the slimmer Eastern bumble bees that enter politely from the flower’s mouth.

    Gelsemium Toxicity

    The toxic alkaloids in all Gelsemium species include gelsemine, but dozens of other alkaloids have been isolated from the genus, which has been studied extensively, pharmacologically. For humans and other animals, all Gelsemiums are harmful (and may be lethal) if ingested in very high, very unlikely doses. These could be self-administered deliberately. Sometime in the second half of the 18th century, the author Sir Arthur Conan Doyle purposefully overdosed on Gelsemium in order to observe its effects in different quantities. He documented his findings and submitted them to the British Medical Journal in 1879.

    The poison may also be ingested via foul play: In 2012, after he died unexpectedly in Surrey, at the age of 44, an autopsy report showed that Russian whistleblower Aleksander Perepilicchnyy had traces of Gelsemium elegans in his stomach.

  • Landscape Architecture Design for a Desert Climate: A Zen Garden in Santa Monica

    Landscape Architecture Design for a Desert Climate: A Zen Garden in Santa Monica

    What happens when a Japanese-style garden meets the southern California desert? For the very Zen results, let’s visit a serene gravel courtyard that landscape architecture firm Terremoto designed for Mohawk General Store in Santa Monica.

    Passionflower vines soften the redbrick facade of Mohawk General Store. “The vines were existing when we started the project and we decided to keep them because they were happy there,” says landscape architect David Godshall.

    “This was an attempt to create a garden that was both Japanese and desert simultaneously,” landscape architect David Godshall says, adding that client Kevin Carney wanted a space to have movie screenings and to create a backdrop for fashion shoots.

    The garden, formerly occupied by gardening shop Potted, had existing hardscape (some concrete slabs) and a few specimen plants—including two large palms—that the team salvaged from the previous design. “For the rest of it, we started from scratch.”

    During the remodel, Terremoto removed “chunky, two-inch gravel and a fair amount of existing concrete” and replaced the surface with decomposed concrete with “a heavy dusting” of gravel on top to stabilize the DG, Godshall says: “With this approach you lose the negative aspects of getting DG on the bottom of your shoes and also the feeling that gravel is a trudge to walk through.”

    “We made the design process conversational,” Godshall says. “We went cactus shopping with the clients. Then we went boulder shopping. After we got all the elements on site, an incredibly hardworking crew shadow boxed them into place. Then there was a lot of looking at how things looked, walking around, and shifting it around.”
