Susan Burke’s home and garden on the Nantucket shoreline off the coast of Massachusetts were designed from scratch when she and her late husband first purchased the property. Featuring tall borders of naturalistic plantings and hardscaping that weave off into nature in the backyard, this space also has a more formal garden in the front yard consisting mostly of native plants. A large dune comes up from the beach, where a buffer of native flora divides the garden from the beach beyond.
