This bunchgrass is often used as an ornamental grass.

It is native to Europe but can be found elsewhere as an introduced species. It is found especially in prairies, at the side of roads and in uncultivated fields. The bulbous variety can be a weed of arable land. It is palatable grass for livestock and is used both as forage (pasture) and fodder (hay and silage); it has high amounts of phosphorus and calcium in its tissues.

Two subspecies have been described:

  • Arrhenatherum elatius subsp. elatius, the more common variety.
  • Arrhenatherum elatius var. bulbosum (also called Arrhenatherum tuberosum), onion couch or tuber oat-grass, distinguished by the presence of corms at the base of the stem, by which it propagates. Occurs in vegetated shingle and arable land.

    Habitat

    Arrhenatherum elatius httpsuploadwikimediaorgwikipediacommonsthu

    Arrhenatherum elatius is a principle species in two UK National Vegetation Classification habitat communities: the very widespread MG1 (Arrhenatherum elatius grassland) and the much rarer MG2 (Arrhenatherum elatius - Filipendula ulmaria tall-herb grassland). This means that it can be found with species such as Dactylis glomerata (also known as Cock's-foot and orchard grass), and of course Filipendula ulmaria (also known as Meadow-Sweet).

    It is found on road verges, along hedges and riverbanks.

    It can colonise and stabilise limestone scree, bare calcareous cliffs, maritime shingle and coastal dunes.
