Sweet potato, Ipomoea batatas, is a warmseason vegetable crop that is widely grown throughout the world. In the United States, commercial production is mainly in the southern states. Many parts of the plant are edible, including leaves, roots, and vines. Tender leaves are a delicacy in a number of Asian and Southeast Asian countries.
