Begonia austrovietnamica

This tuberous species was described in 2018.  I promised myself no tubers, but, this one was too pretty.  It doesn’t do well with drying out (as pictured below, a wilty plant after too much time spent out of a terrarium).  It seems to be on the tricky side, as it’s thin leaves are quick to melt or mold.  Darrin Norton (mountainorchids.com) suggests an 8  week period of no water at the end of the growing season for cycling.
