Begonia fischeri

Fischer's begonia

An unusually tough, fast-growing Begonia found from Mexico and the Caribbean to northern Argentina. It is a succulent-stemmed herb up to 1.5 m, usually short-lived or annual, with small hairy leaves and white to pink flowers much of the year. Unlike most begonias it often grows in full sun on disturbed ground, from near sea level to about 2,600 m, and it self-seeds readily in cultivation.

Where it grows wild

Moonlight and colleagues record it in Amazonian forest, relict montane forest in northwestern Peru, and lower to middle montane forest. It also occurs in permanently wet spots within dry forest and scrub, such as canyons, ditches and below waterfalls. Unusually for a Begonia, it is frequently collected growing in full sun, and it colonises roadsides and disturbed ground.

In Peru it is recorded at 90–2,600 m. GBIF records span 0–2,571 m, median 718 m, mostly from the Atlantic Forest of southern Brazil and the Colombian and Ecuadorian Andes.
