Just coming up along where I planted this basil just not sure if it was or just a weed.

this is basil I planted.

Looks like pigweed to me. Also edible, but I wouldn't even consider making pesto from it. Basil has a pretty unique tell, crush and smell a leaf, and if it doesn't have the right aroma, it's not basil.

It could be amaranth. There are many wild forms. It is used like spinach.

ok found the actual basil growing under this so thinned out the pigweed so basil would grow but where nothing was coming up letting it stay for cover for now.

Good. But when you do pull the pigweed (ie weedy amaranth), if it hasn't gone to flower or woody yet, do be sure to cook it up as spinach.
