Nut tree or something else?

[Elouera]

What is this little tree growing out of the seed/nut? The green seed had a brown husk which has since fallen off. Pecan or something else?

Sorry It looks a bit like a mahonia, shrub, the leaf is very big for a young tree.

It could be a pecan but I don't know, lovely if it is I like pecans

What shape was the seed? Avocado is the usual thing that grows, but their leaves are narrower and a darker green. Whatever it is, it probably won't be winter-hardy, so if you decide to keep it, you'll need to pot it up and bring it indoors over winter.

It's not a mahonia with cotyledons that large - that has come from a big seed, not the tiny seeds inside a mahonia berry.

I just found it growing in the pot, but neighbours may well have left a seed/nut of some sort in the pot after a BBQ (communal space)?

It seems to be growing out of a green seed, about 3cm x1cm oval. It originally had a brown, thin skinned husk which has come off to reveal the green seed/nut in the photo. It looks too small and oval for an avocado seed.

A pecan would be wrinkly.

The seed is now wrinkly, but when the husk was on, it was firm and brown.
