Unknown shrub

Back Blip
I think I had a senior moment last night because whilst commenting I was convinced I had uploaded my Tuesday image - it seems not so...
We have this very vigorous shrub that produces the dangling flowers/bracts, not sure. I can't find anything like it on Google so any suggestions welcome. I think it quite unusual and quite pretty and why it should have a little white flower at the end of the "dangle" I don't know.
