I have had this plant for 5 years, and it has not bloomed since the first summer when I planted it. The blooms that year were blue, huge and beautiful. I had it planted in shade, as instructed, then after 3 years moved it to part shade, but still no luck. The bush itself looks good, but no flowers. I have fertilized it every year, but I skipped this year in case that was a problem.

I was given one of these great looking plants for my Birthday 2011. I think I am going to containerfy it in a large pedestal urn. Maybe get a nice mini forsynthia to place in a matching urn as well. Photos to come.
