Description
A description of Symphyotrichum adnatum is provided in The Flora of North America.
Distribution
Ecology
Habitat
In the Coastal Plain in Florida and Georgia, S. adnatum can be found in longleaf pine savannas, pine flatwood communities, annually burned pinelands, slash pine plantations, and open mixed woodlands.[2] It is restricted to native groundcover with a statistical affinity in upland pinelands of South Georgia.[3] A study exploring longleaf pine patch dynamics found S. adnatum to be most strongly represented within stands of longleaf pine that are between 90-180 years of age.[4] S. adnatum is frequent and abundant in the Clayhill Longleaf Woodlands community type and is an indicator species for the Panhandle Silty Longleaf Woodlands community type as described in Carr et al. (2010).[5]
Soil types include loamy sand and sand.[2] S. adnatum became absent or decreased its occurrence in response to soil disturbance by agriculture in southwest Georgia.[3][6][7]
Associated species include Euthamia minor, Andropogon virginicus, Eupatorium compositifolium, Gnaphalium obtusifolium, Chamaecrista fasciculata, Chrysopsis mariana, Diodia teres, Sericocarpus tortifolius, Aristida, Ctenium, and Sporobolus.[2]
Phenology
This species has been observed to flower from January to November[8], and fruits November through December.[2]
Seed dispersal
This species is thought to be dispersed by wind.[9]
Fire ecology
Populations of Symphyotrichum adnatum have been known to persist through repeated annual burns.[10][11]
Conservation, cultivation, and restoration
S. adnatum should avoid soil disturbance by agriculture to conserve its presence in pine communities.[3][6][7]
