Sweet Potato

Botanical Overview

Sweet Potato (Ipomoea batatas) is a flowering plant in the Convolvulaceae family. The traditional uses of this species reflect its genuine medicinal value, validated by generations of practical experience. This species belongs to the Convolvulaceae family, a group of flowering plants.

General Description

Its sizeable, starchy, sweet-tasting tuberous roots are used as a root vegetable, which is a staple food in parts of the world. Cultivars of the sweet potato have been bred to bear tubers with flesh and skin of various colors. Moreover, the young shoots and leaves are occasionally eaten as greens. The sweet potato and the potato are only distantly related, both being in the order Solanales. Although darker sweet potatoes are often known as yams in parts of North America, they are even more distant from actual yams, which are monocots in the order Dioscoreales.
