Gleditsia triac. iner. Halka

Halka Honeylocust

Gleditsia triacanthos var. inermis ‘Halka’ is a compact, thornless deciduous tree selected for its smaller size and dense, rounded form compared to typical honeylocusts. Fine-textured green leaves emerge in spring, provide a more uniform, lightly filtered canopy through summer, and turn soft yellow in fall, while blooms are small and not ornamentally significant. Its restrained growth and adaptability make it a good choice for residential landscapes and smaller planting spaces.
