Begonia maculata, the polka dot begonia, is a species of begonia native to southeast Brazil. It grows naturally in the Atlantic rainforest, with occurrences confirmed in the Brazilian states of Espírito Santo and Rio de Janeiro.

Care:
The Begonia Maculata needs bright indirect light, well-aerated soil that dries a bit between waterings, fertilization every 2-4 weeks, and temperatures of 18°C to 30°C. They are fussy about humidity and need semi-regular pruning, but they’re very easy to propagate.
