Taxonomic notes
Synonyms: Aster concolor Linnaeus; Virgulus concolor (Linnaeus) Reveal & Keener.[1]
Description
A description of Symphyotrichum concolor is provided in The Flora of North America.
Distribution
Ecology
Habitat
In the Coastal Plain region, S. concolor can be found at the edges of limestone glades, longleaf pine-wiregrass flatwoods, pine-oak-hickory woods, scrub oak sand ridges, edges of brackish marshes, annually burned pinelands, former longleaf pine savannas, longleaf pine-scrub oaks, sandhills, and along roadways.[2] It is restricted to native groundcover and can be found in upland pines of South Georgia.[3] S. concolor is frequent and abundant in the North Florida Subxeric Sandhills and Clayhill Longleaf Woodlands community types as described in Carr et al. (2010).[4]
S. concolor became absent or reduced its occurrence in response to agriculture in South Carolina longleaf woodlands[5] and southwest Georgia savannas and pinelands.[3][6] This species became absent in response to military training in west Georgia pinelands.[7]
Associated species include Schoenus nigricans, Muhlenbergia capillaris, Quercus laevis, Q. incana, Q. minima, Q. margaretta, Aristida stricta, Polygonella gracilis, Smilax auriculata, Licania michauxii, Eupatorium compositifolium, Pinus taeda, Aster adnatus, Ilex vomitoria, Pteridium aquilinum, Polygonella gracilis, Solidago puberula, Liatris gracilis, Chrysopsis lanuginosa, Vaccinium darrow, Warea sessilifolia, Pityopsis graminifolia var. tenuifolia, Liatris chapmanii, Aster linarrifolius, Andropogon, Schizachyrium, Serenoa repens, Smilax auriculata, Solidago odora, Helianthus radula, Tridens ambiguous, Ilex opaca, Baptisia lanceolata, Lespedeza hirta, Petalostemum carolinianum, Agaritina aromatica, Pityopsis aspera var. adenolepsi, and Vaccinium lanuginosa.[2]
Phenology
S. concolor has been observed to flower in January, February, May, October, and November and fruit in October and November.[2][8] Michelle Smith observed this species flowering in April at Quailridge Plantation, in Georgia.
Seed dispersal
This species is thought to be dispersed by wind.[9]
Fire ecology
Populations of Symphyotrichum concolor have been known to persist through repeated annual burns.[10][11]
Conservation, cultivation, and restoration
Symphyotrichum concolor should avoid soil disturbance by agriculture and military training to conserve its presence in pine communities.[3][5][6][7]
