The Honey Locust: An Impressively Armored Species   

Fortunately for those exploring forest in the eastern United States, relatively few of our native trees bear thorns.

There are a few that do – with the devil’s walking stick (Aralia spinosa) being the most obvious example – but even these tend to have relatively small thorns. But the honey locust has giant thorns, which may even branch to form multi-spined clusters. These thorns sometimes reach 4 inches in length, and they represent a legitimate safety hazard to careless nature lovers.

Note that you may encounter thornless honey locusts in unusual places, as they are widely planted in residential scenarios.  

Honey Locust Tree Identification: Tips & Tricks

Because trees with compound leaves are outnumbered by those with simple leaves by a large margin, it’s usually easy to distinguish the honey locust from most other U.S. species, aside from the hickories, ashes, and a handful of others.

For that matter, the honey locust often produces doubly compound leaves, which is an even rarer phenomenon.

But it is the tree’s numerous large spines that make identification pretty easy. The black locust (Robinia pseudoacacia) is the tree that most closely resembles the honey locust, but its thorns are much smaller (generally 1 inch in length or less), and the leaves are rarely doubly compound.
