Passiflora nitida (Bell Apple) is a tasty, but relatively unknown passion fruit native to the Amazon jungle region. This is a rare, really delicious fruit which is much sweeter than any passion fruit. It grows in the tropical lowlands from Costa Rica in the north and French Guiana in the northeast, through wide parts of Brazil. It is similar to P. laurifolia, with orange-yellow fruits that have a sweet, succulent pulp. It is a fast-growing tropical vine. Its flowers are blue and red, a bit like P. laurifolia and P. quadrangularis. The fruits grow up to 2 in. It is tropical and should be protected from frost. The fruits are eaten fresh and very sweet, with no acid, yet very good in flavor. Passiflora nitida is also a useful fruit in a drink called Purple Passion.
