The giant granadilla, barbadine (Trinidad), grenadine (Haiti), giant tumbo or badea, Passiflora quadrangularis, produces the largest fruit any species within the genus Passiflora. It is a perennial native to the Neotropics, having smooth, cordate, ovate or acuminate leaves; petioles bearing from 4 to 6 glands; an emetic and narcotic root; scented flowers; and a large, oblong fruit, containing numerous seeds, embedded in a subacid edible pulp.
The badea is sometimes grown in greenhouses. The fruits of several other species of Passiflora are eaten. P. laurifolia is the water lemon and P. maliformis the sweet calabash of the West Indies.
The fruit juice of the badea is used as a beverage.
A tea is made from the leaves which is used for high blood pressure and diabetes. A drink and ice-cream are made from the fruit.
