Sweetpotato is North Carolina’s top vegetable crop and the official state vegetable. Approximately 50% of the nation’s supply of sweetpotato is produced in North Carolina. Other leading states include Louisiana, California, and Mississippi. Sweetpotatoes are grown primarily in the coastal plain of eastern North Carolina. However, some are grown in northeastern North Carolina (near Edenton) and in the Sandhills area. Small areas (less than 2 to 3 acres) are grown throughout the remainder of the state for home use or sale at roadside stands. The top four sweetpotato-producing counties are Johnston, Nash, Sampson, and Wilson.
