Skyline Honey Locust (Gleditsia triacanthos var. inermis ‘Skycole’): A Thornless Street Tree with a Strong Leader
Skyline is one of the most widely planted thornless honey locust cultivars in North America. It was selected by Barrett Cole in Ohio for a strong central leader, ascending branches, and dense, well-behaved form. The name comes from the clean, upright silhouette.
It reaches about 45 feet tall and 35 feet wide, with a broadly pyramidal habit in youth that opens slightly with age. The doubly compound leaves are fine-textured and fern-like, casting light, dappled shade that lets grass grow underneath. Foliage is medium green in summer and turns a clear golden yellow in fall. The tiny leaflets filter down between grass blades, so fall cleanup is minimal.
Unlike the species, Skyline is thornless and nearly seedless, so there are no dangerous spines or long messy pods. It is a tough urban tree—handling drought, heat, compacted soil, air pollution, and salt once established. Use it as a street tree, lawn shade tree, or in parking lots where a larger, messier tree would not work.
