Yes it's a climbing hydrangea, mine is small at the moment but thriving in the shade. The only drawback is it's not evergreen although I don't think you need to cut it back in the winter so you still have the branches covering your wall, fence etc. Correct me if I'm wrong though and youre supposed to cut it down each year!
Mine was small for years, I didn't cut it at all. It just quietly grew on the neighbours garage wall.
Then suddenly whoomph, it was up in the eaves and onto the roof...we've had to hack it down at the worm time of year. I need to cut it right back after (what remains from recent untimely pruning) flowering I think.
