Description
Distribution
It is found from Massachusetts, south to Texas, east to Florida, and west to Arizona (Weakley 2015).
Ecology
Habitat
Native upland pine and pine-hardwood communities, loblolly pine plantations (Ultisols), borders of wetland depressions within pine communities, sandhills and sand ridges, (Entisols), open calcareous glades, bluffs along Apalachicola River (FSU Herbarium). It can be found in bluestem prairie (Hover and Bragg 1981). It increases with spring burning (Hover and Bragg 1981). It is a warm-season grass (Hover and Bragg 1981). Can occur in areas with soil disturbance (FSU Herbarium). Thrives in frequently burned areas and flowers within two months of burning in the growing season (Robertson observation). Tolerates full sunlight to partial shade. Tolerates moist to xeric conditions but seems to be limited to sandy or calcareous soil. Found barrens of thin soils of rock outcrops (mafic rocks), also in woodlands and sandhills (Weakley 2015) and in flatwoods (Wunderlin and Hansen 2011).
Phenology
It flowers and fruits from April to September (FSU Herbarium; Weakley 2015). It resprouts and flowers within a few weeks of being burned from early spring through summer, but it also flowers in years when it is not burned up to at least five years following fire, primarily in July and August (KMR[1]).
Seed dispersal
Asclepias verticillatahas seed pods that are vertically oriented and disperse seeds by wind after dehiscence (FSU herbarium).
