Hi Porkpal......
If you mean geographically - I am based in the UK, but i'm convinced this is not a native tree. It is in a bed around 100ft from my house and the roots are now spreading under the boundary fence you can see in the photo. The roots are very complex and next door report they cannot dig through them in the bed. Yes the new trees are suckers from the roots and grow immensely fast, they have also begun growing through the lawn and very quickly form strong thick stumps.
Thank you
