Included in A. hyemalis in Michigan Flora.
Occurring in a diversity of habitats, especially in open sandy or rocky areas: on dunes, shores, and rock outcrops; often becoming abundant after fire or other disturbance on shores, jack pine plains, bog borders, etc.; under oak and jack pine; in bogs and on sand barrens.
In this species and A. hyemalis, the culm and panicle branches give an impression of being much straighter and stiffer than in the more lax appearing A. perennans, from which they are quite distinct, although any one of the characters in the key may give trouble. Agrostis perennans has much longer upper leaf blades in relation to the length of the panicle branches than A. hyemalis or A. scabra. Therefore, small specimens of these with panicle branches as short as in A. perennans will have the leaves too short for that species.
