Well, it looks like a form of elder, sambucus nigra f. laciniata (fern-leafed elder), which does occasionally pop up. I have a huge tree of the same which sprouted behind my pond years ago. The way to tell - pinch off a small piece of leaf and crush it. Smell it. If it has a strong sort of earthy or rank smell, then it probably is elder. Let's do that bit first and we'll discuss further if it is!

Wow Worthy, you are good !Just text my daughter so will get back to you when she has 'performed' her bit. :-)

Well she's done her 'bit' and it is definately earthy.She is impressed by the quick response, thanks.
