Close, but no cigar. I, too, picked up Sparks Will Fly this spring, and 
was delighted with how it looked and performed. At some point, I read 
the label and saw the Plant Patent number.

Further reading of the patent revealed several things. First, it is a 
bolivensis hybrid from England. Second, it is propagated from stem 
cuttings. Third, it is sterile, as it only has MALE flowers. Yup, take a 
look at the photos and you will see. Burpee doesn't quite know what the 
story is--I'm sure they are selling tubers as opposed to seed.

I also got a nice fat tuber, and packed it away in peat moss with my 
other bolivensis tubers. They spend the winter in a friend's basement 
that is cool enough to keep them and other bulbs dormant and happy. That 
said, you would probably be okay leaving it in the pot in a cool 
spot--begonias take a good bit of warmth to get going.

The other bolivensis I grow are from the Bossa Nova seed strain, 
acquired as liners--the yellow one is particularly nice. These all 
appear to be fertile, although I've never tried to grow the seed.
