FNA24: "Agrostis perennans 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 A. perennans does not appear to be established in western North America. It is more tolerant of shade and moisture than Agrostis scabra, from which it differs in its later flowering, leafier culms, and its basal leaves that usually wither by anthesis."

This species is considered excluded due to the lack of specimens indicating its presence in the flora.
