Open sandy fields, juniper savannas, and roadsides; occasionally on moister shores. It closely resembles Schizachyrium scoparium and sometimes grows with it, but can be distinguished superficially by the visibly expanded spathe-like sheath largely enclosing the racemes. Old stems color reddish bronze, and are very persistent and conspicuous late into the fall and even until next spring.
This species has clearly increased its range in recent times. Pre-1950 collections are known only from SW Michigan (Berrien and Cass Cos., north to Muskegon Co.). Reported by the First Survey, but no specimens are known.
