A description of Vernonia angustifolia is provided in The Flora of North America.
In the Coastal Plain region, V. angustifolia can be found in sand pine scrubs, longleaf pine-wiregrass flatwoods, edges of meadows, pine-turkey oak flats, longleaf pine savannas, mixed woodlands adjacent to floodplains, annually burned pinelands, longleaf pine-sedge-andropogon savannas, slash pine-wiregrass flats, oak scrubs, second growth hardwoods, cabbage palm hammocks, annually burned upland pines   and sandhill communities.  It can also be found along roadsides, power line corridors, bulldozed pine-oak scrubs, and clobbered slash pine forests. Soil types include sandy loam, loose sand, loamy sands, sandy peat, and Utisols  Associated species include Aristida, Serenoa repens, Ilex glabra, Liatris, Andropogon, Panicum, and Leptoloma cognata. 
This species is thought to be dispersed by wind. 
Seed bank and germination
It can live in areas frequently burned. 
Use by animals
In Southeastern pine savannas, V. angustifolia was found in 6.25% of the active gopher tortoise (Gopherus polyphemus) burrows.
Conservation and management
Cultivation and restoration
