I see this plant growing native along the Delaware coast. It is native along the Atlantic Coast from New England down to SC and some spots along the shores of the Great Lakes. It is the main plant species that holds together the beach dunes at the great vacation destination of Rehoboth Beach. A number of residential yards near the beach have this tall grass growing in the yard or parkway, making a nice naturalistic, low maintenance landscape. Other beach or sandy area plants like Adam's-Needle Yucca, Loblolly or Virginia or Japanese Black Pines, Northern Bayberry, Shiny Sumac, Goldenrods, and others grow and look good with it. The plant is a tall clump, yet spreads quickly through sandy soil to create a colony.
