|discussion=<p>Agrostis hyemalis is most abundant along roadsides and in open pastures, scrub, and rocky areas. It is centered in the southeastern United States; historically it extended north to coastal Maine, where it may be extinct, west to Wisconsin and Texas, and south into the Caribbean, Mexico, and Ecuador. Records from further north and west in North America are confused; many reflect the former inclusion of the generally more northern A. scabra in A. hyemalis. Agrostis hyemalis differs from A. scabra in its smaller spikelets and anthers, more conspicuous culm leaves, and more clustered spikelets.</p>
