Discussion
Stenotaphrum secundatum grows on sandy beaches, at the edges of swamps and lagoons, and along inland streams and lakes. It may be native to the southeastern United States, being known from the Carolinas prior to 1800, but it has become naturalized in most tropical and subtropical regions of the world.
Stenotaphrum secundatum is planted for turf in the southern United States and is now established from California to North Carolina and Florida. Numerous cultivars have been developed. Specimens with variegated foliage (often called S. secundatum var. variegatum Hitchc.) are sometimes used as an ornamental in hanging baskets and greenhouses.
