GLEDITSIA triacanthos f. inermis 'Shademaster'
Thornless Honeylocust
Honeylocust is a spiny, lacy-leaved, medium to large deciduous tree native to the central and eastern United States and southern Ontario. The cultivar 'Shademaster' grows rapidly into a thornless, strong-trunked tree with ascending branches, a symmetrical rounded crown, and dark green foliage that drops relatively late in fall.
Like most honeylocusts, 'Shademaster' has pinnately compound leaves that cast filtered shade. They emerge relatively late in spring and turn 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 resistant to canker, drought, and deer and rabbit damage.
