That was my clump of Chicago Apache, which finished blooming a couple of days ago. It got a really late start this year, and was the last one to bloom. I thought it was finished a week ago, but noticed more blooms on it. I'm positive that it wasn't rebloom. I sure did appreciate it this year, putting on a fantastic show when everything else was done and over with!
Avedon, how nice that you are getting another scape on Wild Horses! It's one of my favorites, but I only had three or four blooms on it this year, and it didn't bother to bloom last year. I also have Persian Market, and love that one also. I bought a double fan of Wild Horses two years ago, and I still only have two fans. Does it increase well for you? I sure wish it would for me. I'd love to have about 50 fans of it!
