It's a weed. I think it's a Chenopodium .

Drat! That makes 2 more dud containers.

Thanks!

It's only a weed if you find it undesireable. Otherwise it's a lovely flowering plant.

Ok enough with the accolades this is a weed. It might be considered a desirable vegetable for some, but in no way
is this a "lovely flowering plant". May of these weeds are
invasive spreaders.
