Begonia ‘Rex’ – Cissus Discolor

A long-time favorite of house plant lovers, Rex Begonia is grown for its colorful, textured foliage.

These fancy- leafed plants (such as the spiral-leaf, pictured below) produce dramatic, large leaves streaked, veined, or splashed in shades of silver, pink, purple, cream, green, or burgundy.

Tiny, insignificant flowers may grow on tall stems. Pinch them off as soon as you see them to keep the foliage looking its best.

This begonia is rhizomatous, growing from a thick, fleshy rhizome that grows just below the surface of the soil. Repot in spring when the rhizome outgrows the pot. Because rhizomes have shallow roots, a shallow pot will do.

Rex begonia can be difficult to grow because of its need for high humidity. Dry, brittle leaves are a symptom of dry air. A terrarium, Wardian case or glass cloche may be just the solution for your humidity-loving begonias.

These fancy-leafed begonias sometimes drop their leaves and become dormant in the winter. If this happens, cut off the withered leaves, stop watering, and enclose the plant in a plastic bag. Keep it at 60°F/16°C until new growth appears, in approximately 6-10 weeks. Then continue with normal care.
