Honeylocust
Gleditsia triacanthos
A tough, adaptable urban tree casting light, dappled shade through fine compound leaves that need little cleanup. Thornless, often seedless cultivars (such as 'Skyline' and 'Shademaster') are planted heavily as street trees, replacing the wild form's vicious branched thorns and messy pods. Tolerant of salt, drought, and compaction but overused, so diversify plantings.

Common questions
Why does my honeylocust have huge thorns and bean pods, but my neighbor's doesn't?
Wild honeylocust has large branched trunk thorns and long seed pods. Landscape trees are usually thornless, seedless cultivars selected to drop the hazards and the litter.
Is honeylocust a good street tree?
Yes — it tolerates salt, drought, compaction, and pollution, and its fine leaflets need little raking. Just avoid over-planting it, since monocultures invite pest and disease problems.
