Distribution
Ecology
Habitat
In the Coastal Plain in Florida and Georgia, S. elliottii has been found in sandy loam of an open slash-pine woodland; wooded ridge; upland, open pine-oak woodland; turkey oak/ longleaf pine scrub; scrub oak sand ridge; annually burned upland pine community; edge of limestone opening; open wiregrass flat in low longleaf pineland; burned upland longleaf pine; annually burned savanna; and on the edge of a limestone glade under Juniperus virginiana.[2] It has been found in disturbed habitats such as camping areas, upland mixed woodland clearings, sand between marshy area and highway, sandy loam field track, sandy soils between pine plantation and highway, and woodland trails. Soil types include loamy sand and sandy loam.[2]
Associated species include Pinus echinata, Pinus elliottii, Pinus palustris, Quercus laevis, Quercus ilicifolia, Aristida stricta, and Juniperus virginiana.[2]
Phenology
It has been observed flowering and fruiting September through November.[2]
Fire ecology
Populations of Sorghastrum elliottii have been known to persist through repeated annual burns.[3][4][5]
Herbivory and toxicology
Sorghastrum elliottii functions as forage for cattle in the late spring and summer; though highly palatable, the species does not hold up well under heavy grazing.[6]
