Calamagrostis arundinacea is a species of bunch grass in the family Poaceae, native to Eurasia, China and India.^[2] Under its synonym Calamagrostis brachytricha it has gained the Royal Horticultural Society's Award of Garden Merit.^[3]

The species is perennial and tufted with short rhizomes and erect culms that are 60–150 centimetres (24–59 in) long. Each leaf has a truncate ligule which is 2–4 millimetres (0.08–0.16 in) long, and obtuse. The leaf-blades are 8–50 mm (0.3–2.0 in) by 1.8–10 mm (0.07–0.39 in), hairless and have both a scabrous surface and an attenuate apex. The panicle has a scaberulous peduncle and is lanceolate, open, continuous, and is 8–18 cm (3.1–7.1 in) long by 1–4 cm (0.4–1.6 in) wide. Flowers have a pair of lodicules and stigmas, and three anthers which are 2.4–2.7 mm (0.09–0.11 in) long. The fruit is a caryopsis with an additional pericarp.^[2]
