Thorny Honey Locust Posted byLance Kleckner October 9, 2005December 30, 2022 Leave a comment on Thorny Honey Locust We have a Honey Locust in our yard that is thornless, but out in the wild, I find very thorny Honey Locusts. As long as I don’t touch the tree, I like the look of these trees, just wouldn’t want to try climbing one.
