Considered endangered. This grass is very heat, drought, wind, and salt tolerant.
Used for erosion control and dune stabilization. Not a great garden grass because it multiplies through long fibrous roots that run.

This is the major dune stabilizing species from coastal Virginia down all through the coast of Florida along the Gulf of Mexico to Louisiana.
