Helping You Become a More Successful Gardener
GLEDITSIA triacanthos f. inermis 'Skycole'(SKYLINE®)
Honeylocust is a spiny, lacy-leaved, medium to large deciduous tree native to the central and eastern United States and southern Ontario. Introduced in 1957 by Cole Nursery of Painesville, Ohio, the honeylocust cultivar Skyline® forms a thornless, strong-trunked, symmetrical tree with a conical crown that becomes dome-shaped with age.
Like other honeylocusts, Skyline® has pinnately compound leaves that emerge relatively late in spring and cast filtered shade. This cultivar's leaves are bronze-tinged in spring, becoming leathery and dark green in summer, and turning dull yellow before dropping in autumn. Fallen leaves create relatively little mess. The trunk has gray-brown, shallowly fissured bark that lacks the formidable spines typical of most honeylocusts. Clusters of inconspicuous greenish flowers appear in spring, with few or no seedpods following.
Honeylocust likes sun and is adapted to a wide variety of soil types. Thornless selections make good shade trees, although overuse of this species has led to increasing cultural problems. This cultivar is reputedly resistant deer and rabbit damage.
