Description
A description of Vernonia gigantea is provided in The Flora of North America.
Distribution
Ecology
Habitat
In the Coastal Plain, V. gigantea has been found in loam soil atop of a ravine; loamy sand in mesic hardwoods; river hammocks; marshes; floodplain forests; upland mixed forest; shortleaf pine-post &red oak-mockernut woods; pine-oak-hickory woods in a ravine; annually burned upland pineland; calcareous slopes; sandy loam in mature hardwoods; sandy open live oak hammocks; sand beneath cabbage palm thicket; calcareous mixed flatwoods hammocks; hammock surrounded by marsh; lowland forests habitats; and sandy peat in a clearing of cabbage palm-live oak hammock (Emery et al. 2011; FSU Herbarium). It is found in disturbed successional areas (Emery et al. 2011) along with moist loam of roadside depressions; loamy sand along edge of channel; open mixed hardwood forest between power-line and road; along powerline corridors; and grassy clearings of pine-palmetto flats. Substrate types include loam, loamy sand, sandy loam, calcareous soils, limestone, sand, and sandy peat (FSU Herbarium).
Associated species include Eupatorium fisulosum, Arnoflossum ovatum, Smilax bona-nox, Morus rubra, Campsis radicans, and cabbage palm (FSU Herbarium).
Phenology
It has been observed flowering January through November and fruiting June through November (FSU Herbarium).
Seed dispersal
Seed bank and germination
Heating at low temperatures stimulates germination in V. gigantea (Emery et al. 2011).
Fire ecology
It has been observed to thrive after low-intensity fires (Emery et al. 2011).
Pollination
Use by animals
Diseases and parasites
