Bromus inermis

Bromus inermis is a species of the true grass family (Poaceae). This rhizomatous grass is native to Europe and considered invasive in North America.

The plant is characterized by an erect, leafy, long-lived perennial, 1+1/2 to 3 ft tall, rhizomatous and commonly producing a dense sod. It starts growth in early spring; flowers May to July; reproduces from seeds, tillers, and rhizomes. It may regrow and re flower in the fall if moisture is sufficient. The leaves are glabrous or occasionally pubescent, particularly on the sheaths; blades 8 to 15 in long, 1/4 to 1/2 in wide, flat, with a raised and keeled midrib below; sheaths closed, except near collar, and papery when dry; leaves rolled in the bud; ligates up to 1/8 in long, rounded, and membranous; auricles absent.
