I got Awesome Blossom in 2009 and I have a picture from 2011 showing that it is still only two fans. I will have to go out and see how many fans it has now, but I am not too optimistic.
Based on the fact that I've had AB seven years and only have 49 pictures of it total (and I take a couple of thousand pictures or more each year of my daylilies), I can honestly say that it is not a heavy bloomer, maybe 8-10 per scape.
I do remember seeing rust on it, but don't think it was too bad.
I just love these reviews because it makes me stop and evaluate the dl's that I have to see if I really want to invest the space to keep some of them. AB is one that I may have to think about getting rid of, although it will be tough because I do like the color of the blooms.
Edited to add: I just had to go out this morning and see how many fans AB had after 7 years in my garden (no dividing and did not give any away). It had a whopping 9 fans! I am pretty sure I only started with 2 fans. However, in its defense, I found as I was digging it up to separate it that there was a one-inch diameter tree root growing next to it and a couple of good sized liatris corms inside the daylily roots. Now that the tree is gone and I've dug out that root, separated the daylilies, and planted the liatris corms elsewhere, I am looking forward to seeing what AB will do in the near future.
