Plant Profile

Gleditsia triacanthos f. inermis (Thornless Honeylocust)

Thornless honeylocust is the landscape variety of Imperial Honeylocust, but thornless and sometimes seedless. Its leaves are both bipinnately compound and pinnately compound, and turn yellow to gold in fall. The seedpods in fall are not appealing and are a litter problem. It has no soil preference and can tolerate compacted soil as well as flooding and confined spaces. Overuse of this tree can lead to insect and disease problems, so plant in moderation.
