Overview

A tropical vine that produces one of the most intensely aromatic and flavorful fruits in the world, with a complex sweet-tart taste and heady tropical perfume. The wrinkled, unpretentious exterior gives no hint of the extraordinary pulp inside, which is used to flavor everything from cocktails to cheesecakes. The flowers are among the most spectacular and intricate in the plant kingdom.
