Description
A description of Liatris elegans is provided in The Flora of North America. A rhizomatous perennial that is frequent where it is found. [1]
Distribution
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.[1] It also can occur in disturbed areas such as powerline corridors, roadsides, and bulldozed sand scrub.[1] Growing in semi-open and open habitats, L. elegans thrives in dry, coarse, and/or loamy sands as well as red clays.[1] 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.[1] L. elegans responds positively to agricultural-based soil disturbance in South Carolina coastal plain communities. This marks it as an indicator species for post-agricultural woodland.[2] When exposed to soil disturbance by military training in West Georgia, L. elegans was shown to respond negatively by way of absence.[3]
Phenology
This species has been observed flowering and fruiting August through November. [1]
Seed dispersal
This species is thought to be dispersed by wind. [4]
