Summary

Sporobolus virginicus, commonly known as beach dropseed or seashore dropseed, is a perennial tussock grass that is naturally found in coastal sand dunes, salt marsh edges, and other saline environments. Its native distribution is extensive, encompassing coastal regions of much of the world. This grass typically grows to a height of 4 to 20 inches and produces inflorescences that are green or purple, with a flowering season that extends through the warmer months. The flowers are not particularly showy but are adapted to the challenging conditions of their native habitats.

Beach dropseed is valued for its ability to stabilize sandy soils with its deep root system, making it an excellent choice for erosion control in coastal areas. It is also used in xeriscaping due to its tolerance of drought and saline conditions. In cultivation, beach dropseed requires well-drained soils and full sun exposure. It is relatively low maintenance. Gardeners should check local regulations before planting in non-native regions, as it may spread beyond intended areas.CC BY-SA 4.0
