I have this pretty one blooming it's head off right now. Trouble is, I don't know it's name, the nursery tag is long gone. Any ideas? Sorry, pic is a bit blurry...

here's another shot of this plant...

Does this look right?

It does. The name is kind of ringing a bell somewhere in my memory also... I think that may be it...
I got it at a nursery I used to work at, and I know we sold that variety... THANKS

Comtesse de Bouchaud was my guess too; once you've had this lovely and showy pink-lavender clematis you'll never forget it. I left mine behind at my old house; perhaps I could find a place to plant it again here - I still see it at nurseries, and most of them have wonderful sales on right now. Well, thank you, you've talked me into it! LOL!

This beauty continues to bloom, bloom, bloom! It is a real looker prettier than its ever been!
