Sweet Potatoes

The sweet potato (Ipomoea batatas) is a dicotyledonous plant that belongs to the family Convolvulaceae. Its large, starchy, sweet tasting tuberous roots are an important root vegetable (Purseglove, 1991; Woolfe, 1992). The sweet potato is only distantly related to the potato (Solanum tuberosum). The softer, orange variety is commonly marketed as a "yam" in parts of North America, a practice intended to differentiate it from the firmer, white variety. The sweet potato is very distinct from the actual yam, which is native to Africa and Asia and belongs to the monocot family Dioscoreaceae. To prevent confusion, the United States Department of Agriculture requires that sweet potatoes labeled as "yams" also be labeled as "sweet potatoes".[1]

And they're probably the most delicious thing Griffith has ever tasted and they can also be used for distinctive orange body art.
