Additional Information

A widely adapted tree with good drought and pollution tolerance, and foliage texture comparable to Gleditsia, but a smaller tree and with more seasonal interest. Relatively trouble-free except for fungi that live in weaker twigs that cause twig blight and canker. Fungi invade most readily those twigs killed by cold or self-pruning. Seeds are poisonous. Difficult to train a central leader. More cold sensitive when young.
