Dry prairies, sand dunes, and jack pine and oak savannas.
Occasionally confused with Sphenopholis, but most easily distinguished by the densely short-pilose rachis and branches of the panicle. In Koeleria, the glumes tend to remain on the pedicels after the rest of the spikelet has fallen; in Sphenopholis, the glumes and pedicel fall with the rest of the spikelet. The anthers of Koeleria tend to be longer (1 or usually 1.3–1.8 mm) than in any of our species of Sphenopholis, except S. nitida.
Though known in the Upper Peninsula from oak savannas in Menominee Co. and dunes on Lake Superior in Marquette Co., an August Farwell collection (bearing one of his infamous "½" numbers) purported to be from Keweenaw Co. is likely mis-labeled and is not mapped.
