I found a poisonous look a like to lambs quarters. It is called deadly nightshade or blackberry nightshade.
Lambs Quarters has leaves coming off north and south like mint. It’s stalk is smooth and hairless. The veins on the leaves are not super noticeable.
Deadly Nightshade has leaves coming off in a circular pattern, looks very much like how a tomato plants leaves and flowers grow. The stem is fuzzy. The leaf veins are very noticeable, either whitish or thicker like plantain.
Glad we checked. They were growing right next to eah other. looked similar enough I almost ate some. Then decided to double check with my Picture This App.
