Elymus elymoides

Bottlebrush squirreltail

Previous scientific name(s): Sitanion hystrix

Formerly known as Sitanion hystrix. Cool season, very drought tolerant, short-lived perennial bunchgrass found on both deep and shallow soils. Easy to establish and often behaves as a pioneer species on disturbed sites. Provides good winter and spring forage to grass grazing animals. Especially useful for revegetation of drastically disturbed sites.

Varieties: 
Sand Hollow

Adapted to a wide range of soil types including sandy soils throughout the Great Basin and northwestern regions of the Great Plains. Good drought tolerance and an excellent seed producer. (Released 1996, source of ecotype: Gem County, ID)

Variety Release Notes: 
Toe Jam Creek

A germplasm having greater seed mass than other accessions. It has a less robust awn making the seed more amenable to de-bearding, resulting in less seed damage from conditioning compared to other releases. (Select class released 2003, source of ecotype: Elko County, near Tuscarora, NV)
