Here in Southern California I have a tree with numerous epiphytes growing on it. During the hottest days of summer I try and water the tree every night...but almost all the epiphytes are completely dry during the day. On the shady side of the tree there is some live moss that manages to grow on clumps of dead sphagnum.
Can anybody recommend any species of Begonia that I might try growing on my tree? Not sure whether I'd have more success with an epiphytic Begonia or with a drought tolerant terrestrial Begonia.
