The official state tree of South Carolina is the Palmetto, from which the state takes its nickname. The Palmetto has long been associated with the history of South Carolina and is represented on the State Flag as well as on the State Seal, where it symbolizes 

the defeat of the British fleet by the fort, built of Palmetto logs, on Sullivan's Island. The Palmetto is an attractive feature of the coastal areas of South Carolina and is also found in Georgia, Florida, and North Carolina                 
Yellow Jessamine, the state flower, is a climbing plant which bears many small yellow, funnel-shaped flowers with a fragrance much like the true Jasmine. It is indigenous to South Carolina and is one of the first signs of spring. South Carolina officially adopted it as the state flower because its "delicate flower suggests the pureness of gold and its perpetual return out of the dead winter suggests the lesson of constancy in, loyalty to and patriotism in the service of the State." 

The Carolina Wren, the official state bird, is present in all areas of South Carolina. Its song can be heard all through the year, day and night. In 1939, the Mockingbird was designated as the official bird of South Carolina, but in 1948, an act was passed making the Carolina Wren the official bird instead of the Mocking bird.

The South Carolina State Quarter is part of the 50 State Quarters Program, which honors each of the fifty states with their own quarter design. Five new quarter designs will be issued each year. The coins are issued in the order in which the states entered the Union. The 2000 quarters honor the states of Massachusetts, Maryland, South Carolina, New Hampshire, and Virginia.
