Honeylocust

Gleditsia triacanthos

Fabaceae · deciduous tree · native

You recognize Honeylocust by its feathery bipinnate leaves creating dappled shade, and its spiney trunk and branches that inspired the common name. The fragrant yellowish flowers appear before leaves in spring, followed by long brown pods. This fast-growing native prefers infrequent deep watering and adapts to poor soils.

Honeylocust tolerates full sun and a wide range of soil conditions, from clay to sand. Plant thornless cultivars where spines are problematic. Once established, it requires minimal watering even in drought. Monitor for stem borers and webworms. The tree's rapid growth and low maintenance make it valuable for difficult sites, though falling pods and leaflets require occasional cleanup.
