It is distributed widely throughout the eastern U.S. and southern Great Plains (NRCS Plants Database). Frequently burned longleaf and shortleaf pine-oak-hickory upland native and old-field communities (Ultisols) (Cushwa 1970, FSU Herbarium), longleaf pine-turkey oak sandhills (Entisols), longleaf and slash pine flatwoods (Spodosols), and limestone outcrops (FSU Herbarium). It is fire-tolerant (Cushwa 1970). Occurs in both native (never plowed) areas and areas with recent recent soil disturbance. Seems to have ruderal tendencies. Occurs on a wide range off soils from loamy sand to to clayey soils and in sites ranging from xeric to moist (FSU Herabarium).
