Popular in the American South, these yellow or orange tubers are elongated with ends that taper to a point and are of two dominant types. The paler-skinned sweet potato has a thin, light yellow skin with pale yellow flesh which is not sweet and has a dry, crumbly texture similar to a white baking potato. The darker-skinned variety (which is most often called "yam" in error) has a thicker, dark orange to reddish skin with a vivid orange, sweet flesh and a moist texture.
Current popular sweet potato varieties include Goldrush, Georgia Red, Centennial, Puerto Rico, New Jersey, and Velvet.
Yams
The true yam is the tuber of a tropical vine (Dioscorea batatas) and is not even distantly related to the sweet potato.
Slowly becoming more common in US markets, the yam is a popular vegetable in Latin American and Caribbean markets, with over 150 varieties available worldwide.
Generally sweeter than than the sweet potato, this tuber can grow over seven feet in length.
