Description

A description of Liatris elegans is provided in The Flora of North America. A rhizomatous perennial that is frequent where it is found.[2]

Distribution

Liatris elegans var. elegans is found from South Carolina through Florida and west to Texas. Liatris elegans var. kralii ranges from southeastern South Carolina through northern Florida Florida and west to southern Mississippi.[1]

Ecology

Habitat

This species has been observed growing in longleaf pine-wiregrass communities, in pine-oak woodlands, bordering sink-ravines, and in live oak hammocks in semi-open to open areas.[2] It also can occur in disturbed areas such as powerline corridors, roadsides, and bulldozed sand scrub.[2] Growing in semi-open and open habitats, L. elegans thrives in dry, coarse, and/or loamy sands as well as red clays.[2] Associated species include longleaf pine, wiregrass, Symphyotrichum dumosum, Solidago, Pityopsis, Liatris pauciflora, Quercus laevis, Heterotheca subaxillaris, Haplopappus divaricatus, Polygonella gracile, Aristidia patula, and Lespedeza hirta.[2]

L. elegans has shown regrowth in reestablished longleaf pine woodlands that were disturbed by agriculture in South Carolina, making it an indicator species for post-agricultural woodlands.[3] However, it became absent in response to soil disturbance by military training in west Georgia. It has shown resistance to regrowth in reestablished longleaf pinelands that were disturbed by these activities.[4]

Phenology

This species has been observed to flower from September to October[5] and fruits from September through November.[2]

Seed dispersal

This species is thought to be dispersed by wind.[6]

Fire ecology

Populations of Liatris elegans have been known to persist through repeated annual burns.[7]
