Begonia boliviensis

Hi Tsuh Yang,
Yes, Begonia bolivensis is tuberous. My tuber came from Brent and Becky's a
few years ago, it is quite large (maybe 5 inches across) and I just
replanted it in a hanging basket outside yesterday. For winter storage in our
climate, I wash and dry the tuber off in fall after the plant has died back, and
pack it in a plastic ziplock bag. I recommend keeping a watch on it or
applying fungicide in case of mold, but so far my tuber hasn't had problems. It is
easy to grow outside, but doesn't like our hottest summer days. I think
there might be a few strains of it around, the BB strain is an older one, I
suspect, but I believe there have been newer introductions from wild collected mate
rial, at least out west.
Good luck,
Ernie D.
