These grasses are tough, coarse perennials with extensively creeping rhizomes. They produce good growth on sands of low fertility, and are used primarily for erosion control in sandy areas. For this purpose, dividing and transplanting clumps of the grasses is the most effective method of establishing stands. If planted not more than 3 feet apart, spaces between plants are rapidly filled in. These grasses are resistant to the cutting effect of blowing sand. They are of little value except for stabilization of sandy soils.
