Cissus discolor, sometimes called Rex Begonia Vine or Tapestry Vine, is an exotic looking trailing vine with colorful lance shaped leaves. The leaves are dark green with silver-white blotches between the veins and burgundy-purple tones along the center vein and edges. The leaves can grow up to 3” to 6” long. The back side of the leaves and the vines of Cissus discolor are dark burgundy-purple colored adding interest to this attractive plant. It is a native tropical plant to Southeast Asia. However, it is also a popular houseplant choice for those looking to add some color and texture to their indoor spaces. Its stunning leaves are sure to make a statement in any room. Despite its common name and resemblance to begonia leaves, Cissus discolor is not a begonia but is closely related to the Vitaceae family (Grape Vine). This plant grows well when given a moss pole or trellis to climb – or when grown in a hanging basket where the vines have room to cascade down the sides. While it is rare when the plant is kept indoors, it can produce small, pale yellow to white blooms. The blooms are insignificant, and the Rex Begonia Vine is grown and prized for its unique colorful foliage and trailing habit. This plant is a medium paced grower that can grow indoors for many years in good conditions. It can grow to heights or lengths up to 6’ – 8’ feet. Cissus discolor is non-toxic to humans and animals, however, it is not recommended for consumption.
Place Cissus discolor in a location that receives bright indirect light. Avoid direct sunlight, which can burn the leaves. The plant will have less vivid coloring if placed in low light areas. Artificial indoor lights can be used to offer more light in low light situations. Use a nutrient rich, well-draining soil mix. You can make a good mixture by combining 50% standard potting soil, 40% perlite for increased drainage, and 10% peat moss for added nutrients. Rex Begonia Vine is susceptible to root rot. Keep the soil moist, but not soggy. Water the plant when the soil is dry about 1” from the top. Wait a few days before watering if the top of the soil is still moist. Be sure to remove excess water from the plant saucer and do not leave the plant sitting in water. This plant also prefers warm (65-80 degrees Fahrenheit) and humid air. Increase humidity if the air is dry. Fertilize once per month through spring and summer according to the product label. Do not fertilize in fall and winter. Cissus discolor usually needs to be re-potted every two years – or when the plant outgrows its current container. Re-potting should be done in spring. Use a container that is one size larger and has holes for good drainage. Use a fresh potting soil mixture as mentioned above. Provide a pole or trellis for climbing or use a hanging basket. Rex Begonia Vine does not require pruning, but it can be pruned or trimmed to shape the plant and encourage additional branching. Pruning should be done at the start of the growing season with sterilized shears of scissors.
Cissus discolor can be infected by common pests including whitefly, mealybugs, and red spider mites. Manually remove the eggs of the Whiteflies. Touch mealybugs with alcohol-soaked cotton ball or swabs. Treat for pests using neem oil, pyrethrum or insecticidal soap products according to the label. Rex Begonia Vine is not sensitive to many diseases when grown indoors. Leaf spots and powdery mildew may be spread by unsterilized pruning shears or scissors. Powdery mildew appears as whitish to gray patches or blotches with talcum-like development. Use a fungicide according to the label. Leaf spot will cause black or dark patches on the leaves that begin as water-soaked lesions and quickly turn black. Remove damaged leaves as they appear and take care not to stress the plant in any other way.
The leaves and stems of cissus discolor produce a natural secretion that creates tiny opaque dots, called cystolyths. While some may think the tiny specks are pests or a disease issue, it is natural and should not cause any worry.
