sweet potato (redirected from Sweet potatoe)

sweet potato, trailing perennial plant (Ipomoea batatas) of the family Convolvulaceae (morning glory family), native to the New World tropics. Cultivated from ancient times by the Aztecs for its edible tubers, it was introduced into Europe in the 16th cent. and later spread to Asia. It is now the most important of tropical root crops and is grown in many varieties (differentiated by their leaf shapes). In the United States it is cultivated chiefly in the South, though a few hardy varieties are grown as far north as Massachusetts. Sweet potatoes are used mostly for human consumption but are sometimes fed to swine. They yield starch, flour, glucose, and alcohol and are especially rich in vitamin A. The sweet potato is sometimes confused with the yam, which belongs to another family. Sweet potatoes are classified in the division Magnoliophyta, class Magnoliopsida, order Solanales, family Convolvulaceae.

Food plant (Ipomoea batatas; family Convolvulaceae) native to tropical America and widely cultivated in tropical and warm temperate climates. Botanically unrelated to the white, or Irish, potato or the yam, sweet potatoes are oblong or pointed oval, tuberous roots. Skin colour ranges from light buff to brown to purplish red; the pulp may be white (highest in starch) to orange (also high in carotene) to purple. Long, trailing plant stems bear funnel-shaped flowers tinged with pink or rose violet. Sweet potatoes are served baked or mashed and used as pie filling.
