Standard crested wheatgrass

Agropyron desertorum

Cool season, long-lived, drought tolerant and extremely cold tolerant, perennial bunchgrass. Adapted to a wide range of sites but is most productive on well-drained, medium textured soils. Similar to A. cristatum but is slightly more cold, shade and moisture tolerant. Also, plants are later maturing and slightly more productive. Good palatability to livestock when green. Introduced extensively throughout the West.
