Begonia polygonoides

An epiphytic, trailing begonia from the rainforests of West and Central Africa, from Guinea and Liberia to Cameroon, Gabon and the Democratic Republic of the Congo. It grows on trunks and branches of forest trees, sometimes 12–20 m up, and on fallen trees, mostly at a few hundred to about 1,600 m. In cultivation it suits a hanging basket or moss pole with warm, humid, airy conditions and a mix that drains fast.
