Poinsett State Park in South Carolina’s High Hills of Santee stands out for its unusual meeting of plant communities from the Blue Ridge foothills, Piedmont, Sandhills, and coastal plain. Long used for hunting by Siouan-speaking Native peoples, the land later included colonial-era holdings and Melrose Plantation, which was destroyed during Potter’s Raid in the Civil War. In the early 1930s, Sumter County donated 1,000 acres for what became the state’s second state park and the first in South Carolina built by the Civilian Conservation Corps. Its CCC-built landscape, segregation-era history, and rich biodiversity continue to define its significance.
