The flag of South Carolina is a symbol of the U.S. state of South Carolina consisting of a blue field with a white palmetto tree and white crescent. Roots of this design have existed in some form since 1775, being based on one of the first American Revolutionary War flags. While keeping most of its design intact since its adoption, it has varied over the years.

Sabal palmetto, also known as cabbage palm, cabbage palmetto, sabal palm, blue palmetto, Carolina palmetto, common palmetto, Garfield's tree, and swamp cabbage, is one of 15 species of palmetto palm. It is native to the far Southeast United States, the Yucatán Peninsula in Mexico, the West Indies, and the Bahamas.
