What is indigo and where did farmers in South Carolina grow it?

Indigo is a deep blue dye derived from the plant Indigofera tinctoria, which was historically significant in the textile industry. In South Carolina, farmers primarily grew indigo in the coastal regions, particularly in areas like the Lowcountry, where the warm climate and fertile soil were conducive to its cultivation. The crop became an important cash crop in the 18th century, contributing to the colony's economy and the transatlantic trade. Indigo was often cultivated alongside rice and used in the production of textiles, making it a valuable agricultural product.
