Anything is possible, but have no idea where it would have come from :) If it is the normal kind (the way the leaves are always severely crinkled am unsure) I need to move it: I think it would love our native oak/hickory forest. There are some of the contorted hazelnuts grown here, but they are sterile (from what I have read).
My tree knowledge consists of; if it has a trunk but no eyes, ears and legs, it's likely to be a tree. But I do recall Hazels in hedgerows on a few farms and it does look a little similar to those. Maybe it will reveal itself a little more once it has grown a bit.
