Bromus inermis, Smooth Brome, is a leafy, sod-forming, perennial, cool season grass that spreads by rhizomes. The stems vary in height from 2 to 4 feet. The plant produces numerous basal and stem leaves that vary in length from 4 to 10 inches. Frequently, the leaves are marked by a transverse wrinkle resembling a “W” a short distance below the tip. The flower head develops a charac-teristic rich purplish-brown color when mature. The seed is produced in semi-compact 5 inch long panicles with ascending branches. The flat compressed seed is usually awnless, about 1/3 inches long, and smooth. There are approximately 135,000 seeds/ pound. Smooth Brome is the most widely used of the cultivated Bromegrasses and has been cultivated in the U.S. since the early 1880s.
