Blue wildrye is an erect, rapidly developing, cool-season (but tolerant of hot weather), native perennial bunchgrass. It grows in small tufts, with broad and flat steel-blue leaves up to 12 inches long. In the Pacific Northwest the bunches rarely exceed 4 inches in width. The spike seed head is commonly blue in color.

Forage Value: Palatable to cattle and horses when young and tender before the seed heads develop.

Historic Uses: Many Native American tribes collected the seeds for food. Because of its thick nodes, this grass was not readily used for basketry.

Miscellany: This grass is very tolerant of fire, as it produces little downward heat thus reducing the damage to its own roots. This is a common grass to include in post-fire restoration seed mixes.

Elymus is from the Greek word elymos meaning 'millet' which comes from elyo meaning 'to cover.'

glaucus is Latinized from a Greek word meaning bluish or greenish grey.
