It has done well here in my zone 6/7 garden. Lovely flowers that look nice, lots of blooms, but I have yet to see the 5 way branching. My main complaint of the plant is lots of blooms, all compacted close together, and it blooms out fast. Beautiful while in bloom, at least when the blooms have room to open up, but it does not last long. Of course, I only have 4 fans so far, a bigger clump could help with that. It has rebloomed each year do far.
