Ammophila breviligulata (American Beach Grass)

Native to the Atlantic coast and the lower Great Lakes, Ammophila breviligulata (American Beachgrass) is an evergreen perennial grass that spreads vigorously through horizontal and vertical underground rhizomes. Growing 2–3 ft. tall (60–90 cm), it may extend 6–10 ft. (1.8–3 m) annually and gradually form extensive colonies.

American Beachgrass is an exceptionally effective dune stabilizer. Its dense rhizome network binds loose sand, while vertical rhizomes produce new stems as shifting sand buries the plant. Stiff, upright culms carry sandy-blond, spike-like flower heads in summer.

Tolerant of heat, drying winds, salt spray, drought, and shifting sand, this iconic coastal grass is the principal species used to stabilize newly forming frontal dunes along the Atlantic and Great Lakes coastlines. It is also valuable for erosion control and initial ground cover on harsh, sandy, non-dune sites, including locations exposed to salinity and dry conditions.

• Grows 24–36 in. tall (60–90 cm) and may spread 6–10 ft. (1.8–3 m) annually by rhizomes. It reproduces primarily through its rhizomes and can form extensive colonies.
• Performs best in full sun in loam or sandy, well-drained soils. Salt-tolerant and drought-tolerant once established.
• Perfect for beaches, sand dunes, and coastal gardens.
• Generally pest and disease free, it requires very little care and provides months of interest.
• Native to eastern North America.
