I know that begonias have both male and female flowers. Are there seeds inside the female flower? Can I dry those flowers and plant the seeds? I'd like to try progagating from seed. I've done it successfully many times via the rooting of clippings. They, of course, always come true to form -- that is, they're actual clones of the original plant. But, I thought that if I could propagate begonias through their seeds, I might just come up with something new and different.
