Interesting Notes about Thornless Honeylocust:

The thornless Honeylocust is a fast-growing shade tree with small, fine-textured foliage creating light shade where grass is easily grown beneth the canopy of leaves.  The leaves are one of the first to defoliate in the fall and are generally not a nuisance for cleanup.  The tree does create surface roots which can be an issue when growing close to driveways or sidewalks.  Honeylocust is named for the sap in the fruit which are long twisting yellow to dark brown seed pods and the quantity varies with cultivar.  This tree is experiencing a general decline due to the insect and disease issues and because it is overplanted is in rapid decline in the state of Kansas.
