Identity of this clematis?
Someone in Worcester has this clematis in their yard and says it has bloomed reliably for years with no maintenance. Of course, she doesn't know the name of it!!!! Argghh! I just love the blue color of this one. Anyone wanna take a guess? Can't get a closer pic, however, if you hit the control key and the plus key at the same time the picture will enlarge for a better look. To make the picture smaller hit control and minus. Pretty tricky, huh? Any and all comments welcome.
