Sweet potatoes are members of the Convolvulaceae family, which includes morning glory. They are native to tropical America and are a perennial plant there. In more temperate regions such as the United States, they are frost-sensitive and grown as annuals. Sweet potatoes are grown for their edible root, which is often mistakenly called a tuber, like white or Irish potatoes (Solanum tuberosum). However, the edible portion of the sweet potato is a true root and will continue to enlarge as long as the plant continues to grow. Sweet potatoes have been grown by Native Americans in Mexico, Central America, Peru, Ecuador, and the U.S. for thousands of years. This bulletin is a comprehensive resource on the production, disease, insect, nematode and weed management of sweet potato.
