I just got into gardening and found this light green seedling with many leaves or like fuzziness on it? The bottom was rounded and scaly-brown looking and this was near a fir tree of some kind, so maybe it was like that?? Thanks

Not a fir tree, I think, but it will be easier to name if you let it grow a bit so the leaves open up.

I agree that it's not a fir. Right now it reminds me of some walnut seedlings I've seen. But it could be something else, as it is still young.

Maple? Please keep us posted as it grows more.
