The sweet potato, which must not be confused with the African yam, thrives around the world and exits in literally thousands of varieties. Although some are poisonous, the species l. batatas is the good one from which all of our various cultivars spring from.
In the US, the variety known as Beauregard is the most common, and is the one we know in the supermarket. A close second is Jewell. These are brown skinned, orange fleshed tubers. But you will find tan skins as well as purple skins. And flesh colors follow the same spectrum: white to orange to purple.
Here is an idea Jerry came up with for you to try, plus some links for further reading.
