Larry, I have Purple Rain Dance, and it does have a couple of fans 10"-12" from the clump. I also have a few other named Daylilies that have one or two fans that are a ways from the clumps, but have never noticed one have a scape or divide into more fans. I have only been growing Daylilies for a few years, so perhaps I just haven't had them long enough. I also noticed that I am having this on several of my three-year-old seedlings this spring, I haven't looked to see if they are siblings yet.
