Bromus hordeaceus is native to the Mediterranean basin, and is now widely distributed across North America, Europe, Africa, and Australia. It grows in waste areas, road verges, fields, grassy plains, and sandy beaches. The grass prefers drained or dry soils consisting of clay loam or sand, especially areas tending to be less fertile. The plant is resistant to drought and temperature variations.
Soft grass reaching 15 to 80 cm in height, leaves flat, the panicle is erect, 5 to 10 cm long, usually with many ovoid-conical tapering spikelets 10 to 25 mm long, usually very hairy on stalks, some of which are shorter than their spikelets, veined. The panicle is branched. Each branch bears only one or two rounded spikelets. Each spikelet is longer than its stalk (peduncle) with three or more florets clearly projecting beyond the glumes. The spikelets are awned. A very variable grass.
