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.
