What is this plant or weed?

I am growing so many things I haven't before from seed, that I have got a bit lost. This came up in my seed compost and doesn't look like anything I've sown, so any ideas would be gratefully received. Thanks.

I think it's a weed known as fat hen 

Omori

Yes fat hen.

Thanks, thought it might be.🙄 Its annoying to find seed compost with weeds already in it.🤨

I doubt it was in your compost, probably a pressie from the birds.

Nope, came out of bags in the conservatory and is yet to leave. So can only have been in the growing medium,  even the pots were new @Lyn

It does look similar to Fat hen, but not quite the same as the ones I’ve spent many hours hoeing out of sugar beet fields. 

There are several members of the same family that are grown as vegetables, ... quinoa, amaranth, lambs quarters. 

Have you sown
anything of the Chenopodium family?

Not that I know of, just looking at a list of them definitely not. Only planted veg and flower seeds.
Dahlia
Verbena bonariensis
Schizanthus
Sweet peas ( which is where two plants showed up)
Tomatoes ( this was a third spot)
So dont think the seed was the problem, do you @Dovefromabove

Nope ... nothing there
