Begonia boliviensis

Ex. 'Santa Cruz Sunset' and Ex. 'Bossa Nova Yellow' cultivars. Surface sow the dust-like seeds on moist potting mix and provide nearly 100% humidity and 70-75 degree temps. Once the seedlings have a little size to them, reduce the humidity very, VERY slowly. The plants are tuberous and don't require high humidity or copious amounts of water once they're mature.
