This legume species from Western Asia produces a honey like sap called ‘gaz’ that was collected by the Persians during Alexander the Great's era. It was made into a candy called Bandar-i-Shah. Massive thorns up to 8 inches long clothe the trunk of the tree. 8 inch pods are produced. Considered a Zone 6 hardiness by most sources, we have found it to be totally hardy at our farm in Michigan and hope our plants soon produce pods. It has hit below minus 20 a few times with no die back.
The yields of the pods and their sugar content may be valuable for both animal and human food and might be kind of a northern substitute of carob or acacia gum. Like all the honeylocust we have planted in our fields, the foliage is browsed on by white tail deer but only the very tips of the branches. The thorns of this tree act as a deterrent to browsing to some extent. Eventually the tree wins out and develops and a rather thick crown.
