A large tussock of coarse growth. Rigid flowering stems to 1 m high. The flowerheads are dense spike-like clusters. Leaves blue-green, 15-40 cm long and 4-15 mm wide, hairless and flat.
Cylindrical seedheads held at the top of long flower stems. Seeds have no awns (bristle).
Perennial. Peak growth occurs in spring and autumn. Prefers fertile, seasonally moist sites. Commonly spreads from pastures, road verges and drainage ditches to adjacent indigenous vegetation. Grows densely and if not grazed or mown, browns off in summer becoming a potential fire hazard.
