|discussion=<p><i>Agrostis perennans</i> grows along roadsides and in fields, fens, woodlands, and periodically inundated stream banks. It is widespread and common in eastern North America; it also grows from central Mexico to central South America. There are old records from Oregon and Washington, but <i>A. perennans</i> does not appear to be established in western North America. It is more tolerant of shade and moisture than <i>Agrostis scabra</i> (p. 646), from which it differs in its later flowering, leafier culms, and its basal leaves that usually wither by anthesis.</p>
