Covington Sweet Potatoes

The Covington is an orange-fleshed, smooth-skinned, rose-colored, table-stock sweet potato developed by North Carolina State University (NCSU).

Sweet potatoes are a great source of Vitamins A, C, and B6, Maganese, Iron and Potassium. They are nutritious and delicious!

Covington sweet potatoes account for 90 percent of the sweet potatoes planted in North Carolina and 20 percent grown nationwide.

Researchers at NC State University’s College of Agriculture & Life Sciences have made their mark breeding better sweet potatoes, most recently with the Covington – named for Henry M. Covington, an NCSU extension specialist who earned the nickname “Mr. Sweet Potato” in the 1950s.
