Description
Wild 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), but die off in winter. The leaves are hairless with blunt ligules. The inflorescence is a panicle with two-flowered bisexual spikelets.

In culture
Arrhenatherum remains are found in northern European burials from the Iron Age but disappear after Christianisation. It has been argued that they are included in the Old Norse category of laukar ('leeks') and may have reflected the rebirth of the dead, or as protection during their journey to the afterlife.
