Description
Distribution
Ecology
Habitat
Within the Coastal Plain this species occurs in a wide range of open habitat conditions, including frequently burned longleaf pine and shortleaf pine-oak-hickory communities,[1] longleaf pine and pine-turkey oak sandhills, Florida scrub communities, pine flatwoods, wet savannas, wet depressions within pinelands, seepage slopes (pitcher plant bogs), calcareous (rockland) slash pine flatwoods, dune swales, shrubby wet prairies, and open cypress swamps.[2][3] Soil conditions include deep sand Entisols, sandy loam Ultisols, sandy peat Spodosols, wet Histosols (peat). This species does well in open, semi shade, and semi open light conditions and grows in large clumps together.
Associated species include longleaf pine, slash pine, wiregrass, turkey oak, Aster adnatus, Sarracenia spp., Ludwigia, Bidens, Sacciolepis, Titi, sweetgum, yaupon, and others.[3]
Phenology
Flowers summer and fall.[4]
Seed bank and germination
In sandhill communities, it suffers from seed germination and radical growth inhibition by allelopathic scrub species during the beginning of the rainy season.[5][6]
Fire ecology
This species is commonly found in burned pine and oak woodlands.[3] Elliott and Vose (2005) initiated a single dormant season burn (low to moderate intensity fire) on a plot containing Andropogon gyrans to see if it would stimulate growth. Additional burning may be required to stimulate its growth and the growth of other bluestem-grasses.[1] Prescribed fire and pine straw harvesting both led to increases in herbaceous plant production (including A. gyrans).[2] It is most common in native communities with minimal soil disturbance. A. gyrans was among the species that responded positively to reduction of woody vegetation using triclopyr herbicide.[7]
