Begonia algaia

Begonia algaia is a rhizomatous begonia of south-eastern China, recorded mostly from Jiangxi with further records in Hunan and Zhejiang. It grows in moist, shaded places in hill forest and ravines. The climate has hot, wet summers and cool winters with nights near freezing at the lowland sites, so it needs a clear seasonal cycle.

Where it grows wild

Few records give a habitat. South-east Chinese begonias of this kind grow on shaded, damp banks and rocks along streams and in valley forest.

Few records carry an elevation. The measured sites range from near sea level to about 1070 m, and most wild plants are probably in hills rather than lowlands.
