Sweet Potato - Tuberous Root

The part of the sweet potato that is eaten is the tuberous root (as opposed to the tuber of the white potato). Because the sweet potato is a root, it lacks "eyes" or buds on the outer surface. Sweet potatoes have orange flesh with a high sugar content. The skin is orange to brown, and the ends of the tuberous roots are pointed. Sweet potatoes are sometimes mistakenly called yams, but true yams are a tropical plant of a different species.
