I just bought a house on Coney Island, 2 blocks from the Atlantic Ocean, with a long, narrow backyard, 20' x 50'. The soil is extremely sandy and exposed to bright sunlight most of the day; the only shade is from two wooden fences, 6' high, on both sides of the property. I am planning to put a flagstone patio and path down, and am also looking for a good groundcover that will take hold in these conditions. I would also like to put down a number of other beautiful plants and am looking for ideas about what might flourish in these somewhat unusual conditions. If you have any suggestions, I would be very, very grateful.
