Trailing foliage plant with striking, black, finger-shaped leaves. Pale mauve flowers may be produced in long summers but the foliage is the main attraction. Can be used in summer hanging baskets or grown as a houseplant. Dies right back to a tuber in winter. Trim back anytime if it gets leggy. Water freely when in leaf but reduce watering when it dies back over winter.

(This a ornamental form of sweet potato, bred for foliage colour and the tubers don't have the crop yield or flavour of the commercial/ agricultural sweet potato.)
