Great color. I had fun looking for a match via pictures and these are the names of ones that look similar.

Abundance
Aljonushka
Inspiration

Thanks for all these suggestions! My best guess is pink mink. I think I will move it this fall and try a montanat in this spot (lots of growing space), but this one is also a keeper!

Aljonushka and Inspiration are both Integrifolia clematis, so they don't climb, but instead make a tall perennial or flop over or lean against other plants. So you can either eliminate those clematis or count them as the only possibilities, depending on whether or not they twine their leaf petioles around supports to climb.

I agree that it looks a lot like Pink Mink with the stripe down the petal center.

Wow, Pink Mink has won the awards. Nice.

Shape and color are wrong for 'Aljonushka'. I does look like Pink Mink
