do mature honey locust not grow thorns?
I was preparing to cut up the top of a large honey locust which had been harvested for timber and I commented to my son that it was one of the thornless honey locust that you occasionally see. He replied that the honey locust must not grow thorns once they get very mature. I wasn't sure about that so I started looking around at other trees and perhaps he's right.
Does anyone have any thoughts on this?
