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.

Days to Germination:


CRNG - Source Identified selection out of Jefferson County, OR.

Pueblo -

Shaniko - Source Identified selection out of Wasco County, OR.

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 earlier releases. (Select class released 2003, source of ecotype: Elko County, near Tuscarora, NV)
