Elymus lanceolatus ssp. lanceolatus (Thickspike wheatgrass)

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 in well-drained soils. Palatability generally good year-round for livestock and wildlife.

VARIETIES & LOCAL ACCESSIONS

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)

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)

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)
