I know I'm pushing zones with this one. I live in zone 5b/6a in NE Ohio. I actually bought this one in NJ when I went to visit my relatives in summer of 2009.
It has done wonderfully, and even bloomed for me this year. I do protect for winter by enclosing it in a wire cage and stuffing with shredded oak leaves.
It blooms in pink, but I would love to see it bloom in pink, purple, and blue, but I don't know if it ever will even if I amend the soil. We'll see... If not then it's lovely just the way it is.
