Gleditsia triacanthos inermis Northern Acclaim

Northern Acclaim Honeylocust

Gleditsia triacanthos var. inermis ‘Northern Acclaim’ is a fast-growing, thornless deciduous tree selected for its improved cold hardiness and upright, oval form. Fine-textured green leaves emerge in spring, provide light, filtered shade through summer, and turn soft yellow in fall, while blooms are small and not ornamentally significant. Its durability and adaptability make it a dependable choice for northern climates, streets, and large landscapes.
