Description
A description of Vernonia gigantea is provided in The Flora of North America.
Distribution
Ecology
Habitat
It can be found in disturbed successional areas (Emery et al 2011). It is commonly found in lowland forest habitats (Emery et al 2011).
Phenology
Seed dispersal
Seed bank and germination
It seems that heating at low temperatures stimulates germination in V. gigantea. It had a 3% average germination rate under control (25 degrees Celsius) conditions, but slightly higher rates when exposed to direct flame (Emery et al 2011).
Fire ecology
It seems to thrive after low-intensity fires (Emery et al 2011).
Pollination
Use by animals
Diseases and parasites
Conservation and Management
Cultivation and restoration
