Natural History: The genus name "Gleditsia" is in honor of Johann Gottlieb Gleditsch, an 18th-century German botanist. The species name refers to the 3-branched thorns. This species has been cultivated since the early 1700’s as an ornamental. The thornless variety 'inermis' is a common ornamental, which we have on campus.
Cultivation Notes: The honey locust has deep roots that do not heave paving. This is a select thornless cultivar, it has a distinct yellow color in the fall. This species has a tall upright form, with a very handsome silhouette. Root rot is very common, as well as mistletoe. They can be very messy, which can contribute to the mistletoe, although it can be manually removed. Growth occurs most in full sun, with low to moderate amounts of watering. They are semi-hardy at 25℉.
Ethnobotany: White-tailed deer and squirrels enjoy the sweet pulpy flesh of the younger pods. These pods are edible for human consumption as well. The flowers also provide a good source of pollen for bees.
