Don't fear the Reaper

Some of the foliage inherited with the house is on a list for the axe man. Some of it has already gone or been cut back. We've often discussed the bush-like plant that grows up the back wall. It never seemed to do much or show any flowerings. So, it put itself in the firing line.

Imagine my surprise when I was in the back bedroom today and this was tapping on the window.

As has been said before neither of us is a knowledgeable gardener, so if anyone knows it's name we'd be grateful.
