Distribution
Ecology
Habitat
It is found in burned and unburned patches of degraded longleaf pine sandhill in the southeastern United States (Heuberger and Putz 2003). This species is also found in pine flatlands, boggy clearings, upland pine-oak woodlands, ravines, along limestone glades, and along riverbanks (FSU Herbarium). It can occur in dry, sandy soils, loamy soils, clays, and moist soils of wetlands in open to partial shaded areas (FSU Herbarium). L. puberula has also been found growing in human disturbed areas such as ditches and along roadsides (FSU Herbarium). Associated species include Pinus palutris, Quercus virginiana, Pinus echinata, Quercus falcata, Helianthus, Eupatorium, Agalinis, Liatris, Coreopsis gladiata, Juncus trigonocarpus, Scleria reticularis, Sphagnum, Pinus taeda, Aristida stricta, and Schoenus nigricans (FSU Herbarium).
Phenology
This species has been observed flowering and fruiting from August to December (FSU Herbarium).
Seed dispersal
Seed bank and germination
Several short-lived perennial forbs also have a seed bank persistent for at least several years (Platt et al 2006).
Fire ecology
This species thrives in areas that are burned (FSU Herbarium).
