This (Gobenia section) Begonia is a spectacular native of Ecuador and Colombia. The species can vary in leaf color from green to, In the best forms, near-black leaves with white spots. Its native habitat is described as subtropical or tropical moist montane forests at elevations of between 3500' to 7800' feet.
As with cultivating other members of the Gobenia section, it prefers humid, terrarium-like conditions yet with room to run/climb where possible. I provide it a lightly damp (not wet) growing medium and ALMOST allow it to dry between waterings (but never in low humidity).
Like with others of this section, they are prone to rotting if too wet and sometimes known to decline when too hot. They can, however, rebound surprisingly quickly once growing conditions are restored to its' range of preference.
I grow it in my basement, under reasonably bright artificial light, in a covered container, in media thats layered with drainage, then sphagnum moss, promix, perlite, and topped again with a thin layer of moss.
Offered here as established clumps in 3" pots.
