Dry or sometimes moist sandy open ground, especially prairie habitats and along railroads. The culms grow in small tufts from a stout rhizome, which tends to be more distinct in this species than in its relatives.
The type was collected in Michigan by Dr. Ithamar B. Crawe, presumably near Pontiac (Oakland Co.) where Crawe lived from ca. 1837–1840, although the collection (K) lacks a date and specific locality. Another unusual, though very indirect, connection to Michigan botany is that Crawe died tragically in the line of duty, drowning in Perch Lake, New York, while gathering plant specimens to fill a request from Asa Gray – but after Gray had left Michigan for Harvard.
