My Stella that didn't rebloom was a true Stella. I divided it and gave some of it to a couple of neighbors, and it rebloomed for them. It just didn't like me! One neighbor planted hers in conditions that were pretty much identical to where it was in my yard, so that is the only thing I can come up with! I have one here at our new house, and it may be reblooming, but I've been gone so much since we moved that I haven't had time to really pay attention to it.
