Bromus carinatus Hook. & Arn. (B. breviaristatus [Hook.] Thurb., B. carinatus vars. linearis Shear and marginatus [Nees] A.S. Hitchc., B. hookerianus Thurb., B. marginatus Nees, B. sitchensis var. marginatus [Nees] Boivin)
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.
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.).
Coarse textured, free-draining soils.
soil reaction salinity
Prefers dry, moisture-deficient sites but tolerates some moisture (S. Bastin, personal communication).
Sun to light shade (S. Bastin, personal communication).
bec zone subzone status
Excellent species for dry sites and for stabilizing banks and slopes.
Can be invasive/aggressive. Can be effective and attractive (S. Bastin, personal communication) as a single drift at the back of a border. Good all season character.
