Charleston Tea Plantation, Tea plantation in Wadmalaw Island, US.

Charleston Tea Garden is a tea farm on Wadmalaw Island, about twenty miles south of Charleston, South Carolina. Its 127 acres of Camellia sinensis bushes are grown from clones and kept in straight rows, and a sign at the entrance reads "Welcome to the Charleston Tea Garden". The grounds hold the fields, a processing factory and a visitor centre, all owned by the Bigelow Tea Company.

French botanist André Michaux brought Camellia sinensis to the United States in the late 1700s and gave plants to Henry Middleton, who grew them at his plantation. Later attempts in Georgetown, Greenville and Summerville all failed within twenty years. In 1960 Lipton bought the Pinehurst Tea Plantation in Summerville and in 1963 moved its research station to Wadmalaw Island. Mack Fleming and Bill Hall bought the land in 1987; Bigelow Tea bought it at auction for $1.28 million after 2003.

The garden's name changed from Charleston Tea Plantation in June 2020, partly to make clear it has no link to antebellum slavery. Its American Classic Tea has been the official tea of the White House since 1987. Visitors can join tea tastings and the First Flush Festival, formerly held each spring to mark the start of harvest.

The farm offers guided tours through the cultivation fields and the processing facility, where you can see the individual steps of tea production. The visitor center has a small exhibition and a shop where local teas are available to take away.

The bushes are grown from clones rather than seeds, so every plant on the 127 acres is genetically identical and the flavour stays consistent from season to season. Mack Fleming, while working for Lipton, built the Green Giant, a cross between a cotton picker and a tobacco harvester that cuts the top layer of leaves and is still used for harvesting from May to October.
