Notes. Often used as a lawn grass.
Very similar to F. rubra, and difficult to distinguish from it, particularly if the base is not complete.
Although commonly referred to as F. nigrescens in Australia, the status and correct name of plants referred to this name is uncertain. The history and publications relevant to Chewing's Fescue are discussed by Aiken et al. (1996 onwards).
Introduced. Usually in drier open habitats, e.g. roadsides, pasture. Flowers Nov.-Jan.
