A perennial, warm season, native grass reaching heights of 2 to 4 feet. Leaves are green to blue-green in color and narrow, long, and rough. The seedhead is a raceme 3 to 5 inches long, silvery to creamy or silky white when ripe. It is considered to be good forage for wildlife and livestock when green but tends to become unpalatable when dry. Ideal for seeding arid southwestern landscapes. It is best suited for plantings on silty or clayey soils and is drought tolerant. It is found in the southwestern United States and Mexico.
