BROMUS biebersteinii (Meadow brome)

Formerly Bromopsis biebersteinii. Cool season, perennial open sod-former with short rhizomes. Adapted to most sites where water is adequate but performs best on moderately deep, well-drained moist soils. Long-lived and very winter hardy. Primarily used as a pasture component in grass and grass-legume mixtures. Spring green-up is 2-3 weeks earlier than other common pasture grasses. Excellent year-round forage. Use in dryland pastures in areas receiving greater than 14 in. of annual precipitation. Varieties listed below.

Days to Germination:


Cache - Enhanced seedling establishment and increased yields on both irrigated and semi-irrigated pastures in the western U.S. Improved forage production under drought. (Released 2004, origin: Regar, Fleet and Paddock varieties)

Fleet - Similar characteristics and pasture yields to Regar but slightly more resistant to silver top; also higher seed yields. (Released 1987, origin: Regar variety & Eurasian sources)

High West - Developed from populations with increased crude protein content and forage yield. Use on both irrigated and semi-irrigated hayfields and pastures in the western U.S. (Released 2017)

Macbeth - Similar in forage production to Fleet, Paddock and Regar, but with significantly higher seed yields. (Released 2001, origin: MT)

Paddock - Slightly more resistant to silver top than Regar. Similar pasture and hay yields to Fleet and Regar; seed yields are slightly lower than Fleet. Good vigor and winter hardiness. (Released 1987, origin: Krasnador, former USSR)

Regar - Seeds germinate and establish quickly. Very winter hardy and produces abundant forage. (Released 1966, origin: Turkey)
