CRITIQUE
The native species of honey-locust has large thorns on its stems and bark. For this reason, thornless honey locust, also known as Gleditsia triacanthos f. inermis, is most commonly sold. For the sake of species diversity, it should only be planted after careful consideration of alternatives. The species may be difficult to find in nurseries. Most nurseries will carry the thornless form.
