View prices and availability
Medium-size tree with a narrow pyramidal crown, up to approx. 13 m. Because the trunk grows a straight central leader with little forking, it forms a regular crown. The thornless twigs are olive green, while the older bark is smooth and grey-brown. Grows thicker than other Gleditsia cultivars. The compound leaf emerges late. It is glossy dark green, turning golden yellow in autumn. Does not blossom very profusely, so produces hardly any fruit. Easier to cultivate in comparison to other Gleditsias. Very good street and avenue tree: can grow amid paved surfaces. Also suitable for industrial areas.
