Smooth brome is a cool-season perennial grass valued for pasture and hay production, forming dense stands of blue-green foliage. It is drought-tolerant once established and requires minimal maintenance, making it useful for erosion control and rangeland restoration.

Why grow it

Smooth brome establishes quickly compared to native cool-season grasses and provides reliable forage production across a range of soil types. Its deep root system and drought tolerance once established make it practical for erosion control and rangeland seeding in northern climates where cool-season species are preferred. Extension services commonly recommend it for pasture renovation and hay production where perennial stand persistence is the primary goal.

Watch out for

Smooth brome can be slow to reach productive biomass in its establishment year and may require adequate soil moisture during germination. Stand density declines over time without management, and it competes poorly against vigorous broadleaf weeds during establishment, so weed control in early growth stages improves long-term success.
