Sweet potatoes (Ipomoea batatas) are a staple food crop originating in the Americas, specifically in Central and South America. Archaeological evidence indicates that the region’s indigenous people have been cultivating sweet potatoes for over 5,000 years. The crop was widely cultivated by indigenous groups in the Andes Mountains, where they served as a primary food source.
European colonizers and traders spread the sweet potato to other parts of the world, including the Caribbean and Africa. The crop was introduced to Europe in the 16th century and was later brought to the United States by Spanish and English settlers. Sweet potatoes became an important food crop in the southern United States, particularly in states like North Carolina and Louisiana, where they were grown for subsistence and export.
