Botanical illustration of Hackberry
Tree · Celtis occidentalis

The unkillable native shade tree for the worst sites — it takes drought, wind, salt, alkaline clay, pollution, and neglect, which is why it thrives on prairies and city streets alike. It hosts several butterfly species and makes small sweet berries (a real edible, historically ground into a Native food) that birds devour. Not showy, just tough, fast, and ecologically rich — a great choice where nothing else grows.

Hackberry is commonly eaten and isn't considered toxic, but "commonly eaten" isn't a guarantee for any particular person or animal — allergies, quantity, and which part you eat all matter. One caveat on this one: Berries edible and safe. Never eat a plant you haven't positively identified, and check with a vet before letting pets or livestock graze anything new.
