Arrhenatherum elatius (L.) P. Beauv. ex J. Presl & C. Presl ssp. elatius[HC2]

Origin: Introduced

selected vouchers: WTU

Notes: FNA24: "Arrhenatherum elatius is grown as a forage grass and yields a palatable hay; it does not withstand heavy grazing. It readily escapes from cultivation and can be found in mesic to dry meadows, the edges of woods, streamsides, rock outcrops, and disturbed areas such as fields, pastures, fence rows, and roadsides. Varigated forms with the leaves striped green and white or yellow are cultivated as ornamentals. There are two subspecies, both of which have been found in the Flora region. Plants in which both lemmas have long, geniculate awns have been called A. elatius var. biaristatum (Peterm.) Peterm., but do not merit formal taxonomic recognition.

Arrhenatherum elatius subsp. elatius is more common than subsp. bulbosum. It is not known whether the two have different ecologic or geographic distributions in North America."
