The American Beachgrass is native to the Atlantic Coast from Newfoundland down into North Carolina, even South Carolina and around the shores of the Great Lakes. It is a quickly spreading grass that colonizes sand dunes with lateral and deep roots. It is wisely being planted by beach communities into the dunes that are between the ocean beach and the boardwalk and town to protect from ocean surges during storms. I think it is a beautiful grass. It also grows in naturalistic front and back yards that are near the shore area in sandy soil. In coastal Delaware Beachgrass shares the dunes and sandy soil areas with Adams-needle Yucca, Seaside Goldenrod, Northern Bayberry, Beach-Heather, and such, with Loblolly Pine, Virginia Pine, Eastern Redcedar, Southern Red Oak, Winged Sumac, and Little Bluestem not far behind.
