California brome (photo by Toni Corelli)

Can be invasive/aggressive but is effective and attractive as a single drift at the back of a border. Good all-season character. Do not over-fertilize in a landscape setting or the plant will become over-aggressive and control may be required. Photo by Toni Corelli.

Geographical Range and Habitat Requirements

Ecological Setting: 

A variety of open habitats in B.C., south through Washington, Oregon to California. Occurs through boreal, temperate, cool, semi-arid and marginally summer-dry mesothermal climates. More a Cordilleran species than a coastal species, except in the dry Coastal Douglas-fir zone. Increases with increasing temperatures and decreases with increasing precipitation (Klinka et al.).

Soil Texture: 

Coarse textured, free-draining soils.

Moisture Regime: 

Prefers dry, moisture-deficient sites but tolerates some moisture (S. Bastin, personal communication).

Shade Tolerance: 

Sun to light shade (S. Bastin, personal communication).
