Begonia wallichiana

A small, weedy, succulent-stemmed begonia with white flowers, native to eastern and southern Mexico and Guatemala. It grows in limestone sinkholes, on rock walls and cliffs, in cloud forest with coffee and in disturbed ground, mostly below about 1100 m. It is easy, short-lived and self-seeds, and it has naturalised elsewhere.
