Wild Flower or Weed

This is a flower that is growing in our garden, we have about 10 of them and they are now about 6ft tall. They have so many flowers on them but I am still unsure what they are.

They are so pretty, I wouldn't mind them in my garden. Seems that Jo has managed to identify it for you.

I should have known that it was the height that threw me. Nice capture.

Very soft greens and purple flower. I've never seen these before.
