The Thornless Honey Locust is a sizable deciduous tree that can grow between 30 to 70 feet tall. True to its name, it lacks the thorns found on its parent species, Gleditsia triacanthos. This tree belongs to the legume family and features a short trunk with a broad, spreading canopy. Its finely textured, pinnately compound leaves contribute to its graceful appearance. For optimal growth, it should be planted in full sunlight within moist, nutrient-rich, well-drained soil, ensuring there is ample space for its full size at maturity.
This flowering tree provides light shade, making it suitable for planting grass beneath it. In the fall, the small leaflets drop, simplifying cleanup. It is easy to transplant and can thrive in poor clay soils, as well as withstand salt, drought, and the presence of black walnut. Additionally, it is resistant to deer damage. The wood of the Thornless Honey Locust is notably dense and durable when in contact with soil, capable of achieving a high luster finish, which makes it an excellent option for lumber and furniture projects.
The genus name Gleditsia honors the German botanist Gottlieb Gleditsch, while "triacanthos" is derived from Latin, meaning "three-spined," and "inermis" translates to "unarmed."
In terms of pests and diseases, borers and webworms can pose challenges. Honey locusts are also vulnerable to leaf spot, canker, witches’ broom, powdery mildew, and rust.
