Not much of a common name for this rather remarkable Asiatic vine with small white citrus-scented flowers and greenish globular edible fruits. Plants of both sexes must be present for fruit production, but it is the male that is chiefly grown for its large heart-shaped leaves which become variegated with cream and rose–the effect seldom occurring until the plant is a few years old. Growing to 15 feet it is hardy to zone 4.
