Dune Grass, also known as American Beachgrass and Marram Grass, is a spreading, rhizomatous native bunch grass common along the shores of Lake Michigan. Dune grass is often used as an erosion control plant for dune stabilization or on non-dune areas where soils are sandy and dry. Dune grass is attractive to many homeowners because it requires minimal maintenance—no mowing necessary, and once established, this native plant requires no irrigation or fertilizer. Dune grass requires a sunny location and well-drained soils.
