Begonia radicans

Brazilian heart begonia

A trailing to scrambling epiphytic begonia from the Atlantic Forest of southeastern and southern Brazil. A 2025 study showed that Vellozo's original Begonia radicans is the plant long grown as B. solananthera; the scandent coral-flowered plant sold as 'B. radicans' is B. limmingheiana. Both come from the same forests and need similar care. It suits a hanging basket or a mounted position in bright shade with steady moisture.

Where it grows wild

An epiphyte and scrambler in the humid Atlantic Forest, including the montane forest of the Serra do Mar, growing on trunks, rocks and banks.

Records run from the coastal lowlands (Itanhaém, Caraguatatuba) up into the Serra do Mar, roughly sea level to about 1000 m.
