Bromus inermis* (Smooth brome)

Cool season, moderately drought tolerant, long-lived vigorous sod-former. Adapted to deep soils. Very productive; starts growth in early spring, ripens by early summer and produces abundant late-summer and fall regrowth. Highly palatable to livestock when green, fair palatability to wildlife.

Days to Germination:


Carlton - A leafy, high yielding forage variety used for hay and pasture. Also a candidate for reclamation having demonstrated a tolerance to contaminants in industrial soils. Considered to be best suited to the northern U.S. High seed yields. (Released 1961, source of ecotype: nine clone synthetic of northern common smooth brome; western Canada)

Lincoln - Aggressive, develops strong rhizomes and forms sod. Considered to be best suited to the southern half of the U.S. (Released 1942, source of ecotype: Hungary)

Manchar - A mild sod-former which does not become sod-bound as quickly as Lincoln. Used throughout the mountain west and northern latitudes of the U.S. (Released 1943, source of ecotype: Manchuria, China)
