Taxonomic notes

Synonyms: Lobelia amoena var. amoena[1]

Varieties: none[1]


"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."[2]

"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."[2]


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.[1]



This species grows in floodplain forests, semi-open wetlands, along river and stream banks, seepage bogs, and low depressions.[3] It grows in shaded to deeply-shaded environments in wet or dry sands and loam of mesic wooded environments.[3] L. amoena also grows in human-disturbed areas such as roadside ditches and clear-cut woods.[3]

L. amoena became absent in response to soil disturbance by heavy silviculture in North Carolina longleaf pinewoods.[4] It also became absent or decreased its occurrence in response to agriculture in southwest Georgia pinelands.[5] It has shown resistance to regrowth in reestablished pinelands that were disturbed by these practices.[4][5]

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.[3]


This species flowers from late July to October.[1][6]

Fire ecology

This species has been found in annually burned areas.[3]

Conservation, cultivation, and restoration

L. amoena should avoid soil disturbance by heavy silvilculture and agriculture to conserve its presence in pine communities.[4][5]
