My clematis is in its third year (sleep, creep, leap...yay!) and is looking pretty happy. Of the three clematis I have, this is the only one I don't know the name of. As a reference, my Niobe bloomed first and is still going, then this one bloomed a couple weeks later, and my Comtesse de Bouchaud is still in buds.

I recently noticed a few yellowing leaves and thought I'd come to the forums and see what you all thought about these photos. Can anyone tell me what is going on with this plant? And what steps do I need to take to remedy this condition?

Thank you in advance for any help (or possible variety IDs) you all may have to offer!
