Elymus lanceolatus ssp. lanceolatus

Thickspike wheatgrass

Previous scientific name(s): Agropyron dasystachyum, Agropyron dasystachyum var. riparium, Agropyron dasystachyum var. riparum, Agropyron elmeri

Formerly known as Agropyron dasystachyum. Strongly rhizomatous, long-lived, drought tolerant, perennial sod-former similar in appearance to Pascopyrum smithii but ripens about 3 weeks earlier. Adapted to a wide range of sites but does best on well-drained soils. Palatability generally good year-round for livestock and wildlife.

Varieties: 
Bannock

A composite selection derived from six accessions in several western states. A long-lived, leafy variety with vigorous sod producing qualities. Superior drought tolerance and forage production. (Released 1995, source of ecotype: OR, WA, ID and CA)

Variety Release Notes: 
Critana

Developed for strong sodding ability in dry sites. Very strong seedling vigor - great for site stabilization including sand dunes. (Released 1971, source of ecotype: Havre, MT)

Variety Release Notes: 
Schwendimar

Selected for adaptation west of the Rocky Mountains. Produces more forage and is more drought tolerant than Critana. (Released 1994, source of ecotype: The Dalles, Oregon)
