Helping You Become a More Successful Gardener
GLEDITSIA triacanthos f. inermis 'Impcole'(IMPERIAL®)
Honeylocust is a spiny, lacy-leaved, medium to large deciduous tree native to the central and eastern United States and southern Ontario. Imperial® is a compact, round-crowned, unarmed selection introduced in 1956 by Cole Nursery of Painesville, Ohio.
This cultivar has dainty, bright green, pinnately compound leaves that cast filtered shade. The foliage emerges relatively late in spring and turns dull yellow 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. Imperial® produces few or no seedpods.
Honeylocust likes sun and is adapted to a wide variety of soil types. Thornless, sterile selections make good shade trees, although overuse of this species has led to increasing insect and disease problems.
