Description
A description of Vernonia angustifolia is provided in The Flora of North America.
Distribution
Ecology
Habitat
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 [1] [2] and sandhill communities. [3] 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[2], and Utisols [4] Associated species include Aristida, Serenoa repens, Ilex glabra, Liatris, Andropogon, Panicum, and Leptoloma cognata. [2]
Phenology
It is a fall forb. [5] Showy-flowered sandhill species. [3] Flowers and fruits June through October. [2]
Seed dispersal
According to Kay Kirkman, a plant ecologist, this species disperses by wind. [6]
Seed bank and germination
Less than 1% of V. angustifolia seeds remained viable after two years of burial. [4] So V. angustifolia does not have a short-term persistent soil seed bank and has little seed dormancy. [4]
Fire ecology
It can live in areas frequently burned. [4]
Use by animals
In Southeastern pine savannas, V. angustifolia was found in 6.25% of the active gopher tortoise (Gopherus polyphemus) burrows.[1]
