Looks like Meadowsweet, Filipendula ulmaria. A wild flower in the UK, but only a guess.

thanks

it is growing into a big bush

Hi, my first thought was Deutzia, maybe magnifica, but I wouldn't stake my life on it, Derek.

thanks derek

This is White Snake Root (Ageratina Altissima). Be careful with this one; it's toxic. Keep animals especially live stock away from it. I'm always hearing about Mary Todd Lincoln (Abe's mom) who died from ingesting milk from cattle that grazed on this.

thanks

I'm sorry Abe's mother was Nancy Lincoln (Mary Todd was his wife). Here is an article about it you might find interesting.
