Bromus tectorum


Annual or winter annual grass.
Cheatgrass has a fine, feathery appearance overall, with slender light-green stems drooping at the tips where the seeds form. Seed spikelets and their bristles can be 5 centimetres long. Mature grass grows to 75 centimetres and turns first purple, and then brown, as it dries.

Cheatgrass can be troublesome in winter wheat and other crops. Seed bristles may injure livestock and animals' eyes and mouths, but provides good spring forage before seed-set.

In British Columbia, cheatgrass is common in southern parts, but rare elsewhere. It grows at low- to mid-elevations at the coast, and in the grasslands and dry forests of the Interior. It is common in recently burned rangeland, winter crops, disturbed areas, abandoned fields, eroded areas, and overgrazed grasslands.

Seeds are dispersed short distances by wind, but the awns (seed bristles) can attach to fur or clothing.
