Where it grows wild

It grows in the understory of lowland broadleaved forest near the coast of northern Palawan, unlike some related Palawan begonias of hill forest. Rosette begonias like this one usually sit on shaded banks and rocks where the canopy is closed.

GBIF records span 30-500 m, with a median of 30 m, which fits its described lowland seaside habitat.
