Seaoats once blanketed the coastal landscape along the southeastern United States from North Carolina to south Florida. Now they are endangered. They were the primary dune stabilizer and will grow right up to the high tide mark along the beach. Plants spread by means of underground rhizomes. Each plant develops a showy inflorescence about 5 feet tall. The oat-like fruit persists on the plant, giving the plant a nice texture as the wind blows. Existing plants should be saved wherever possible, and planting should be encouraged along the beaches.
