|Natural range of Lobelia amoena from USDA NRCS Plants Database.|
Common name: southern lobelia
Synonyms: Lobelia amoena var. amoena
"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. Leaves elliptic to lanceolate, 4-15 cm long, 2-4 cm wide. Sepals entire or remotely glandular-serrate; corolla tube 7-9 mm long; filament tube 5-7 mm long. Capsule 6-8 mm broad."
This species ranges from western North Carolina and eastern Tennessee to western South Carolina, central Georgia, and east-central Alabama. There are disjunct populations in the Florida Panhandle and the Coastal Plain of Georgia and South Carolina.
This species grows in floodplain forests, semi-open wetlands, along river and stream banks, seepage bogs, and low depressions. It grows in shaded to deeply-shaded environments in wet or dry sands and loam of mesic wooded environments. L. amoena also grows in human-disturbed areas such as roadside ditches and clear-cut woods.
L. amoena became absent in response to soil disturbance by heavy silviculture in North Carolina longleaf pinewoods. It also became absent or decreased its occurrence in response to agriculture in southwest Georgia pinelands. It has shown resistance to regrowth in reestablished pinelands that were disturbed by these practices.
Associated species include Boltonia, Commelina, Coreopsis integrifolia, Physostegia virginiana, Woodwardia areolata, Quercus, Rhamnus, oakleaf hydrangea, Conoclinium, Pluchea, Leersia, Panicum, Schoenus, Juniperus, Solidago fistulosa, and Bidens alba.
This species has been found in annually burned areas.
