The Vitaceae is a family of 13 genera and around 800 species including many tropical and subtropical climbing plants, with stems usually bearing tendrils which are positioned opposite to a leaf. The grape vine Vitis vinifera is an economically important non-succulent species, cultivated throughout human history for its juicy fruit, much of which is fermented into wine.
The fruit of a number of other species of Vitis is used for jam, wine and grape juice. However, fruit of some genera of Vitaceae (e.g. Virginia creeper Parthenocissus quinquefolia grown as an ornamental) contains oxalate which is poisonous to mammals, although not to birds.
Succulent genera: Within the family Vitaceae, only species of Cyphostemma and Cissus have succulent members, in some cases with a caudiciform or pachycaul habit. They need to be kept warm, especially when small. Bunches of small grape-like fruit are produced, but the berries are hard and inedible and may be poisonous.
