Begonia masoniana Begonia masoniana, the iron cross begonia, is a species of plant in the family Begoniaceae, native to New Guinea. It is a rhizomatous perennial begonia growing to 0.5 m , bearing large, asymmetrical, textured green leaves covered in reddish hairs, with a prominent dark brown pattern in the centre of each leaf, reminiscent of the German Iron Cross.
