Clematis: Clematis Finally Bloomed!, 1 by Weezingreens

About 4 years ago, a friend gave me two clematis. They bloomed in their little boxes, but once in the ground, they ceased. The following spring, only one survived, and not it is quite a healthy plant. I'd just about given up seeing it bloom, but the foliage was nice. The other day I walked past the clematis, and there was a bloom!

For you vine and climber folks, this probably seems pretty uneventful, but in our Zone 3 area, clematis are marginally successful... mostly tangutica, or Golden Clematis. This one is a lovely white with a tinge of pink and and dark, bluish center. After all this time, I have no idea which cultivar it is, but it sure looks like a Miss Bateman. What do you think?
