Gleditsia triacanthos ‘Skyline’®, commonly known as Skyline Honeylocust, is a popular landscaping tree valued for its graceful, upright form and fine-textured foliage. This deciduous tree produces strikingly bright green pinnate leaves that turn a golden-yellow in fall, adding seasonal interest. 'Skyline'® is well-adapted to urban environments, thanks to its tolerance of pollution, compacted soil, and high heat. It is seedless, which makes it a cleaner choice compared to other honeylocust varieties. Its broad canopy provides excellent filtered shade without overly dense coverage, making it ideal for residential and commercial applications.
