The piedmont physiographic region of South Carolina covers about a third of the state and is composed of rolling hills.  Natural habitats range from dry upland communities and granite outcrops through mesic slopes to seasonally wet floodplains.  Plant species present vary greatly with soil composition and moisture; thus, allowing for a high diversity of species. Visit key areas in the piedmont region with experienced educator Dr. Charles N. Horn.  Basic Botany is required.
