Begonia hatacoa

A branching, cane-like Himalayan begonia 30-65 cm tall with narrow, long-tipped, asymmetric leaves that are brown-hairy beneath. It grows on rocks in shaded, moist spots on forested slopes and beside streams from Nepal to Vietnam. The silver-leaved form sold as 'Silver' is the one most often grown.

Where it grows wild

According to the Flora of China, it grows in evergreen broad-leaved forest, on rocks in shaded, moist places on slopes or by streams. Specimen labels mention overgrown rock walls in shaded, narrow creek valleys and rocks at landslide edges.

1,200-1,500 m in Xizang (Flora of China). Records elsewhere extend lower into foothill valleys, for example around 750-1,300 m in eastern Nepal.
