Sweet potato

Ipomoea batatas

Fruit & vegetableHarvestCompanionsLookalikes

A tropical morning-glory grown for its sweet orange (or white, or purple) storage root — not a yam, not a potato.

Sweet potato is an Ipomoea, a morning-glory of tropical America. The kitchen crop is the swollen root, cooked. Traditional West African, Caribbean, and Southern tables treat it as a staple. It is not Dioscorea (true yam) and not Solanum tuberosum. Leaves are a cooked green in some kitchens; this plate is the root.

Flavor

Orange types are pumpkin-honey. White types are drier, chestnut. Purple is a pie.
