Cissus discolor, native to Java and Cambodia, is a fast growing, exotic looking, trailing vine, which is sometimes called Tapestry Vine or Rex Begonia Vine. It is not a begonia, but the medium sized lance shaped leaves have the bright colors of Rex Begonia leaves. The leaves are dark green with silver and purple blotches. It makes a gorgeous hanging basket. Thanks to its large, striking leaves and climbing growth, Cissus discolor has become a popular houseplant. The leaves and stems produce a natural secretion, tiny opaque dots, called cystolyths. Grow this Cissus in a hanging basket or let it climb up a trellis.
