About

Causonis clematidea, known as the native grape, slender grape and bushy water vine, is a vine in the grape family that is native to the tropical and subtropical regions of eastern Australia. It produces dark, glossy grape-like berries.

Where it grows

It is found growing in the wet sclerophyll forests and woodlands from the Shoalhaven River gorges in southern New South Wales, to northeastern Queensland in the tropical forests at around the Townsville area. It thrives within humid, shaded areas, where it can be seen climbing over rocks and shrubs, usually on rainforest margins.

Uses

Preferring full sun to part shade, it can be useful for cultivation in the garden as the blackish berries and tubers are edible, although the berries do not have a strong flavor. Moreover, the flowers attract birds and moth caterpillars to the garden. Historically, Aboriginal Australians used the tubers of the native grape and as well as Cissus opaca as a "yam", where they prepared the tubers by pounding them on stones before roasting them.
