Ecology
Habitat
In the Coastal Plain, T. chrysophylla habitats include longleaf pine-oak-wiregrass woodlands, sand pine scrubs, pine/wiregrass communities, scrub oak wiregrass sandhills, and upland turkey oak longleaf pinewoods. It has been found in disturbed areas such as along logging roads, a clear cut disturbed longleaf pine scrub oak ridge, an open sand ridge plowed three years previously, a bulldozed clearing in turkey oak longleaf pine, a sandy old quarry, a clobbered slash pine forest, and coarse sandy clearing of longleaf pine scrub oak barren. Soil types include loamy sand, sand, and sandy peat.[3] Associated species include Balduina angustifolia, Dalea feayi, and Polygonella robusta.[4]
Phenology
Flowering occurs June through September and fruiting May through October[3].
Fire ecology
It has been observed growing in burned pine flatwoods[3].
