Chilean Zabala Fruit Lardizabala funaria

For its foliage, for its flowers and for its fruit, this plant from Chile is just full of interest. A very handsome and vigorous, twining climber, it has very ornamental, dark green, glossy, leathery leaves (some folk grow it just for this) and bears very late in the year drooping clusters of very striking and fascinating, dark chocolate flowers.
The Flowers are followed by equally fascinating, dark purple, sausage-shaped fruits two or three inches long. The fruits are sweet, pulpy and edible and are sold in markets in Chile where they are much appreciated.
Although they will tolerate a temperature as low as 14°F (-10°C), give it the warmest, most sheltered spot in your garden. A cool unheated greenhouse will do just as fine.
