It grows to 50–150 cm tall, with leaves up to 45 cm long and 1 cm broad. The leaves are hairless,rolled rather than folded, and the lower sheaths turn dark brown. It has no stolons or rhizomes, no auricles. The flowerhead is 7–15 cm long and 8–10 mm broad, with densely packed spikelets. It flowers from June until September. The stamen are pink.
It is commonly grown for cattle feed and, in particular, as hay for horses. It is relatively high in fibre, especially when cut late. It is considered a harsh, course grass little relished by livestock if cut earlier. It is considered part of the standard mix for grass hay and provides quality nutrition for horses.
