General Description

Attractive green leaves with a light glossy finish and shaped like a more rounded grapeleaf, Begonia reniformis displays upright, wipsy clusters of white flowers intermittently year round. A tender perennial native to Brazil, this species is regarded as a thick-stemmed begonia, growing tall, fleshy stems that rarely branch and can become quite wood-like with age.

The leaves are bright medium green and held out on love, grooved petiole stems in a horizontal manner. Each leaf blade is rather round, but with irregular and jagged lobes that make it resemble a grape (Vitis) leaf. From the tips of the main upright stems will form an upright, widely branched white flower spike cluster that will dangle tiny white male or female blossoms. Flowering occurs year round but most heavily from late winter to autumn in flushes. The fruits are small and light green to tan in color and will dry and split open while dangling on the white flower spike. Very old stems become quite woody and may snap off from their own weight and are replaced by new, unbranching stem canes from the roots in the clump.

Grow grapeleaf begonia in dappled sunlight to partial shade in a humusy, moist sandy soil that has good drainage. Never allow the plant to be in soggy or flooding soil conditions. It is a lovely tall accent for a mixed tropical shade border or as a container plant; the container must be heavy to prevent toppling. Consider staking plants outdoors if they are exposed to light winds.
