30 Honey Locust Gleditsia triacanthos
Sometimes known as the thorny locust. It is believed the thorns were developed to protect the tree from the mammoths and other huge animals that roamed North America in the last ice age around 30,000 years ago. The tree is a legume with edible pods. The leaves turn yellow in Autumn before they fall. There is another Honey Locust near the flying fox in the children’s playground which is a Whanganui protected tree.
