(Gleditsia triacanthos)

Thornless-Honeylocust_1-852You may recognize the resemblance the thornless honeylocust shares with its relatives the honeylocust and the waterlocust of the deep South— minus the sharp thorns that cover its branches. The thornless honeylocust is popular for its ability to grow in urban stress areas such as parking lot islands and sidewalks. In fact, it has become so overused in some cities that it has become discouraged to plant to prevent monoculture. When too many of the same species are planted it can increase the threat of pests and disease.
