It also seems to be hardy in zone 3... as many campanula species are.

I've had this cultivar for several years. In my garden, it is not nearly as invasive as the straight species. It blooms fairly late in the summer, some 3-4 weeks after the straight species has finished.

From the research I've done on this plant there are descrepencies regarding hardiness zones. I guess I'll wait to see if mine comes back up in the spring. It did very well for me in the garden all summer, likes a sandy well drained soil.
