thanks for the replies friends )
the messages from both Sacha & Steve are excellent and give great information. I'm tempted to lift it right away but don't want to lose the beautiful flowers on it just now so I'll think I will just wait until the autumn and then do the big lift. You know, this is an excellent site and looking through the other posts I've found lots of very practical help - just brilliant.

I might even take a photo of another shrub/bush and post a link to it to ask if anyone knows what it is - but at a later date.
again, thanks for the help guys see you later )
