Some retailers that sell sweet potato plants include Southern Exposure Seed Exchange and Scott Farms. Customers can order organic sweet potatoes from New Sprout Organic Farms.
Southern Exposure Seed Exchange sells slips of sweet potatoes. They typically produce about 1 pound per plant. These slips can be transferred into a garden each spring. Scott Farms uses a method called micropropagation to make sure their sweet potatoes are free of viruses before shipping them to consumers. This process gives stronger yields and creates a more uniform final product. New Sprout Organic Farms sells four varieties of organic sweet potatoes, including Covington, New Orleans, Murasaki and Garnet.
