Bromus marginatus

Mountain brome

Previous scientific name(s): Bromus breviaristatus, Bromus carinatus var. linearis, Bromus marginatus var. breviaristatus, Bromus marginatus var.

Cool season, short-lived perennial bunchgrass, adapted to a wide spectrum of relatively moist soils including thin, infertile sites, but is intolerant of high water tables. Establishes quickly and easily on disturbed sites. Common on foothills and mountain valleys and has good shade tolerance. Good palatability to livestock and wildlife. Performs well at high elevations.
