Taxonomic notes

Varieties: Vernonia angustifolia Michaux var. angustifolia; Vernonia angustifolia Michaux var. mohrii S.B. Jones; Vernonia angustifolia Michaux var. scaberrima (Nuttall) A. Gray.[1]

Description

A description of Vernonia angustifolia is provided in The Flora of North America.

Distribution

Ironweed is found throughout the southeastern coastal plains region from North Carolina to Florida to Mississippi.[2]

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[3][4] and sandhill communities.[5] 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[4], and Utisols[6] Associated species include Aristida, Serenoa repens, Ilex glabra, Liatris, Andropogon, Panicum, and Leptoloma cognata.[4]

V. angustifolia reduced its occurrence in response to agriculture-based soil disturbance in South Carolina's historically longleaf communities.[7] It has shown resistance to regrowth in reestablished pinelands that were disturbed by agricultural practices, making it a possible indicator species for remnant woodlands.[8] V. angustifolia became absent in response to military training in west Georgia pinelands.[9] It also decreased its occurrence in response to soil disturbance by agriculture in southwest Georgia.[10]

Vernonia angustifolia is frequent and abundant in the North Florida Subxeric Sandhills community type and is an indicator species for the Clayhill Longleaf Woodlands community type as described in Carr et al. (2010).[11]

Phenology

V. angustifolia is a fall forb.[12] Showy-flowered sandhill species.[5] It has been observed flowering in January and June through October and fruits June through October.[4][13]

Seed dispersal

This species is thought to be dispersed by wind.[14]

Seed bank and germination

Less than 1% of V. angustifolia seeds remained viable after two years of burial.[6] So V. angustifolia does not have a short-term persistent soil seed bank and has little seed dormancy.[6]

Fire ecology

It can live in areas frequently burned.[6]

Pollination and use by animals

Vernonia angustifolia has been observed with leafcutting bees such as Megachile mendica (family Megachilidae).[15] In Southeastern pine savannas, V. angustifolia was found in 6.25% of the active gopher tortoise (Gopherus polyphemus) burrows[3] and is a nectar plant for native pollinators.[16]
