Principal trees of South Carolina include palmetto (the state tree), balsam fir, beech, yellow birch, pitch pine, cypress, and several types of maple, ash, hickory, and oak; longleaf pine grows mainly south of the fall line. Rocky areas of the piedmont contain a wide mixture of moss and lichens. The coastal plain has a diversity of land formations—swamp, prairie, savannah, marsh, dunes—and, accordingly, a great number of different grasses, shrubs, and vines.
