I've had WOW for 5 years now and even though I don't see a lot of WOW factor, it is a nice garden plant. My daughter and I split the double fan when we bought it, so my single fan may have turned into eight by now.
It has mostly two-way branching and not a huge amount of buds, maybe 10-12. Here in southern Indiana, it begins blooming around mid-June and only blooms for about 2 weeks, maybe a little more.
Upon closer inspection of my pictures, I see that this beautiful gold edge and diamond dusting may be the reason why WOW has 143 children. Maybe it does have a WOW factor, after all
