Compared to exotic animals, wild greens should not scare anybody, at least as it comes to the taste. Toxicity is something else, however. I am sure you already check out the edibility of these plants.
Yup, I am careful.
My father was very good at plant identification and we ate things from cattail root to wild mushrooms. I would not trust myself on the mushrooms so I have not eaten any except morels and puffballs for for years.
