Description
Distribution
Ecology
Habitat
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).
Phenology
In the southeastern coastal plain it flowers in September and October and fruits September-November (FSU Herbarium).
