Begonia bipinnatifida is very neat looking Begonia, mainly because it doesn't even look like a Begonia and looks more like a fern!
Begonias do not need any direct sun, though do need a bright filtered light to keep them happy. They also like to be watered when the 2-3 inches is dry which is roughly every 7-10 days. If they ever wilt, usually they will pop right back up within a few hours of watering! If ever repotted, they do best a HEAVY ratio of perlite to soil. Though we have found best results for growing begonias to be avoid repotting altogether. We found this begonia appreciates extra humidity!
