The terms "sweet potato" and "yam" are often used interchangeably; however, they are actually two entirely different crops. Only sweet potatoes (Ipomoea batatas) are grown in the U.S.; yams (Dioscorea spp.) are grown in the Caribbean and many other tropical areas. The most profitable marketing opportunities for sweet potatoes in Kentucky are through local fresh markets, such as farmers markets, direct delivery and CSA, and on-farm stands. Producers also market through local wholesale channels, selling directly from the farm to restaurants, grocers and institutional foodservice, including schools.
