I wish I'd purchased more of these bulbs when I bought my three. Hopefully they'll multiply and I'll eventually have a great clump like yours!
I'm learning patience as a gardener, I guess.

I started out with 3 bulbs too. Only one has divided so far that I can tell. I have a neighbor that really wants one, so I dug it up last spring, but didn't feel like it was ready to divide yet, so she will have to wait. One of my favorites and always gets a lot of comments from passerbys.
