Begonia formosana
A large, cane-stemmed rhizomatous begonia endemic to Taiwan and the Ryukyu Islands, with broad, shallowly lobed leaves up to about 25 × 29 cm (sometimes silver-spotted) and white to pink flowers from June to October. It grows in shaded, moist forest, ravines and gorges from the lowlands into the foothills. Grow it warm and humid in summer with bright shade, and cooler with less water in winter.
Where it grows wild
Flora of China describes it as growing in forests in shaded, moist places. It is common in the wet valleys around Taipei and in gorges on Taiwan's east coast; the Taroko gorge form was once named Begonia tarokoensis. It grows on the ground, on moist banks and on rock faces in shade.
Flora of China gives 700–900 m, but many records come from much lower wet valleys near Taipei and on the east coast (about 100–400 m), and some from Yangmingshan near 800 m.
