Ammophila arenaria (European beachgrass) is a clumping perennial grass (family Poaceae) found in coastal dune systems from Santa Barbara County north. European beachgrass grows more densely than native American dunegrass (Leymus mollis), trapping passing sand and creating steep dunes that run parallel to the shoreline.

European beachgrass (Ammophila arenaria) is a perennial rhizomatous grass occurring in coastal dunes. Stems are clumped, stiff, and upright. Leaves are twelve to forty-four inches long, thick and waxy. The outer surface is smooth and light green; the inner surface has ridges and is covered with a whitish coating.

Scientific name: Ammophila arenaria The dense, spiky tufts of Marram grass are a familiar sight on our windswept coasts. In fact, its matted roots help to stabilise sand dunes, allowing them to grow up and become colonised by other species.

Ammophila arenaria is a cool-season, coarse perennial grass with deep, tough creeping rhizomes. It grows well in areas where sand shifts and actively buries plants. It has stout stems up to 90 cm tall and long leaf blades and dense, spike-like panicles of flowers.

Ammophila arenaria is a European species that has become naturalized in most temperate countries. It was introduced along the Pacific coast and in the interior of western North America as a sand binder.

Ammophila arenaria threatens coastal sand dunes in the eastern and western United States. It displaces native dune species and significantly alters the morphology of dune systems where it invades.

Habitat: Sandy beaches and dunes along the coast. Flowers: June-August. Origin: Introduced from Europe. Growth Duration: Perennial. Conservation Status: Not of concern. Pollination: Wind. Culms in tufts up to 11 dm. tall, connected by tough, elongate rhizomes.

Ammophila arenaria is a perennial grasslike herb that is not native to California. [Cal-IPC] Invasive: Ammophila arenaria (European beachgrass) is a clumping perennial grass (family Poaceae) found in coastal dune systems from Santa Barbara County north.
