Yes...clematis pitcheri. Unfortunately, the vine was partly attached to a small tree that had died last year. The base of the tree trunk snapped and I had to get the vine off it this evening so I could remove the little tree. I should have removed that tree early in the year. But I procrastinated, then when the hummingbirds came...well, they like to rest on the branches...then the clematis vine grabbed onto it...oh, well!
