Which plant is this?

Hi , this plants is growing in a pot . Do you know which plant is it? Is it edible?

I think nightshade, I wouldn't suggest you eat it until you're sure

Black nightshade (Solanum nigrum)

Agree with William on black nightshade. When it gets flowers and berries we can give you a positive ID, which is cool because this one is edible! Leaves and fruit. believe it or not.

I also see some purslane growing in there, another edible.
