Description
editWild forms can resemble wild oat (Avena) or fescue (Festuca). Oat-grasses are very common perennials with yellowish roots. The shining stems grow to a height of 1.80 m (6 ft),[8] but die off in winter. The leaves are hairless with blunt ligules. The inflorescence is a panicle with two-flowered bisexual spikelets.[9]
