Description
Common name: tall ironweed
Distribution
Ecology
Habitat
V. angustifolia was found around 6.25% of the active gopher tortoise (Gopherus polyphemus) burrows observed by Birkhead and his team (Birkhead et al 2005). It can live in areas where dominant soils are Utisols (Coffey and Kirkman 2006). It can be found in pine savanna communities (Birkhead et al 2005). It is a common occurrence in longleaf pine communities (Coffey and Kirkman 2006; Brewer and Cralle 2003). It is also associated with sandhill communities (Heuberger et al 2003).
Phenology
It is a fall forb (Kirkman et al 2004). Showy-flowered sandhill species (Heuberger et al 2003).
Seed dispersal
It is dispersed by wind (Kirkman et al 2004).
Seed bank and germination
Less than 1% of V. angustifolia seeds remained viable after two years of burial by Coffey and Kirkman (2006). Thus, V. angustifolia doesn't have a short-term persistent soil seed bank and has little seed dormancy.
Fire ecology
It can live in areas frequently burned (Coffey and Kirkman 2006).
