About this plant
Gleditsia triacanthos 'Imperial'® (commonly known as Imperial Honeylocust) is a graceful, medium-sized deciduous tree prized for its fine-textured, bright green foliage that turns a clear, golden-yellow in fall. This thornless cultivar grows in a rounded, moderately dense habit, providing light filtered shade, which makes it excellent for home landscapes, streetscapes, or parks. Its adaptability to urban areas, resistance to pests and diseases, and tolerance to pollution make it an ideal choice for challenging sites. No prominent flowers but valued for its beautiful foliage and refined appearance.
