Common name: Downy lobelia
Synonyms: Lobelia puberula var. puberula; L. puberula var. simulans Fernald; L. puberula var. mineolana F. Wimmer
"Perennial or annual herbs, stems erect, strict or freely branched. Leaves crenate, serrate or entire. Raceme terminal ,bracteate, often very leafy and the flowers appearing axillary. Calyx 5-lobed, more or less actinomorphic; corolla zygomorphic, fenestrate, 2-lipped, upper lip 2-lobbed, lower 3-lobbed. Stamens 5, completely united. Capsule dehiscent by apical pores. Seeds yellowish brown, tuberculate, oblong, 0.6-1 mm long." 
"Similar to L. elongata. Stems pubescent, at least near the base. Leaves elliptic, lanceolate or oblanceolate, 3-12 cm long, 1-4 cm wide. Calyx lobes lanceolate, rarely linear, 5-10 mm long, sometimes slightly auriculate, entire or with callous-tipped teeth; corolla tube 7-10 mm long; filament tube 5-8 mm long. Capsule 6-8 mm broad." 
It is found in burned and unburned patches of degraded longleaf pine sandhill in the southeastern United States.  This species is also found in pine flatlands, boggy clearings, upland pine-oak woodlands, ravines, along limestone glades, and along riverbanks.  It can occur in dry, sandy soils, loamy soils, clays, and moist soils of wetlands in open to partial shaded areas.  L. puberula has also been found growing in human disturbed areas such as ditches and along roadsides.  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. 
Seed bank and germination
Several short-lived perennial forbs also have a seed bank persistent for at least several years. 
This species thrives in areas that are burned.
