We planted three of these in our zone 6 yard last summer, because they claimed to be cold hardy and our big-leaf hydrangeas were having trouble. This spring two of the Tiny Tuff Stuffs had died to the ground, and the third had died all together. It was an unusual winter, with a warm February and cold March, but we were very disappointed. The regular big leafs died to the ground too, but seem to be coming back more vigorously.
