The height ranges from 40 to 120 cm (47 in). The panicle is 7–20 cm, usually nodding and often spreading,[4] but erect as first.[5] The leaf-sheaths are hairy, the upper are usually hairless.[5] B. commutatus is stouter than B. racemosus, the smooth brome, with a flower-head not drooping to one side and a broader elongated branched flower head.[6]
It is found in meadows, wasteground, road verges, hayfields and rough grassland.[7] Found throughout the United Kingdom, it is common in England on the moist soils of water meadows; it is rare in Scotland, Ireland and Wales.[3] It is found naturally throughout Europe, N. Africa, W. Asia. It has been introduced into North America and in the United States is known as 'Hairy Chess'. The flowering period is from May to July.[3]
The species has no fodder value in the United Kingdom and is regarded as a weed. The attractive inflorescences may be used, either fresh or dry, in flower arrangements.[3]
Bromus commutatus var. pubens Wats has spikelets which are not hairless, having soft hairs.[3]
