    • Additional Information

    The Shademaster Thornless Honeylocust is a popular cultivar that is nearly fruitless and has dark green, finely compound leaves on ascending branches that provide a pleasant, dappled shade in the summer. The thornless forma inermis is only sold in commerce, as the profuse thorns of the species type can be a liability. Mimosa webworm and locust mite are serious pests in the Midwest, and are becoming more serious (especially in areas tending toward monoculture). Can be controlled with spraying.
