Description

Distribution

Ecology

Habitat

It is distributed widely throughout the eastern U.S. and southern Great Plains (NRCS Plants Database). Frequently burned in 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 in limestone outcrops (FSU Herbarium). It is fire-tolerant (Cushwa 1970). Occurs in both native (never plowed) areas and areas with recent recent soil disturbance. Some seem to have ruderal-growing tendencies. Occurs on a wide range of soils from loamy sand 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).

Seed dispersal

Seed bank and germination

Fire ecology

It thrives in frequently burned (1-2 year interval) habitats and occurs primarily in high-light environments but can also tolerate partial shade (FSU Herbarium).
