Begonia arborescens

Begonia arborescens is a shrubby Atlantic Forest begonia from south-east Brazil, especially Rio de Janeiro state, growing to about 1.5 m with masses of small white flowers. Specimen notes place it in shaded, wet dense rainforest on trail edges, rocks and stream banks, from near sea level to about 1300 m. It suits a warm, bright room or greenhouse, with slightly cooler, drier winters.

Where it grows wild

Specimens describe it as a shade-loving terrestrial herb or shrub about 1.3–1.5 m tall. It grows in moist soil in dense ombrophilous forest, on trail edges, and on rocks beside streams in well-shaded spots. Its leaves are membranous, sometimes slightly sticky, and green above and paler or red beneath.

Records span 0–1312 m, with a median of 530 m (64 records), mostly in the coastal ranges around Rio de Janeiro such as Tijuca, Tinguá and Petrópolis.
