What tree is this?

[Outwith]

It was growing in my acer's pot!

Oh, that's the wrong photo 🤣.

That's a fern of some description.

This is the right photo.

No photo!

No photo!

Oh no - I can see photos on the app! Are you on the web version or the app? I posted the wrong photo to begin with 🙈.

It looks rather Salix like, do you have any willows around?

Once the leaves have come out properly, you'll have a better idea.

No willows that I know of - I'll try to keep it alive (I removed it from the pot with the acer!), and see what it turns into 😄🤞🏻. Thanks!
