Guide
The species-level account. Cultivar pages build on this and say where they differ.
Begonia masoniana is a rhizomatous Begonia from the warm, humid understory of Southeast China and Vietnam, where it grows in dappled shade with steady warmth and moisture. Give it bright indirect light, never direct sun, and water when the top inch of mix has dried — its shallow rhizome rots if left sitting wet. It prefers high humidity and airflow; let the surface approach dryness between waterings rather than keeping it soggy.

16–26 °C
Loose, well-draining mix rich in coir or peat with perlite
Leaf or rhizome cuttings in humid, moist medium
Dilute balanced feed monthly through spring and summer
Slow
Grown for its puckered leaves; flowers are small and secondary
Toxic to cats & dogs
Soluble calcium oxalates — mouth irritation, vomiting; tubers most toxic. This is where toxicity lives: every cultivar of this species inherits it and none can override it.
