It looks a bit like Hypericum androsaemum, which is a native plant that has the typical Hypericum flowers and then berries that mature through green/red then black.

Looks strong and determined. So interesting to see what turns up isn't it? Sorry I can't help though.

It looks so strong and determined that, if you didn't plant it, I'd have it out ASAP.
Willow seedling?

It could be the start of a fruit tree, apple or plum, not sure, hard to tell, but as it is in a pot let it grow for a while and you may be able to tell later on. Dont think its hypericum.

I am inclined to go with Beattie and suspect a willow seedling.

Is it something that the Squirrels Buried lol.

If it's from a willow, the seeds blow about all over the place. Little fluffy things that lie about in great mounds like cotton wool.

WILLOW. Worthy

Thanks for all your help..... could be a willow i suppose i have willow trees.... but the leaves dont look like this at all.... will be interesting to see how it turns out....

I agree Holly, I dont think its willow either, its a suprise tree, waiting to be identified!!
