They are self fertile, so even if you only have one
plant, you can get it to
seed. You have to pollenate them by hand - I use a little paintbrush that came with my son's watercolor kit. Then you just wait. The
flower petal part will die leaving the main stem from the bulb, the 4 (or 3 or 2) little stems that went to the actual
flower, and the "blob" (pod?) at the end with the developing
seeds. It's not particularly pretty at this point, but so what? I didn't look so great when I was pregnant, either. Anyway, when the pod-thing starts to turn tannish brown and get dry, you've got viable
seed! If you know someone who has a different colored one blooming when yours is, bring home some of its pollen in a baggie (or whatever) and cross them. That'll make waiting the few years for the
flowers (what color will they be?) more interesting. Good luck!
