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.
