The classic and trusted book “Fifty Common Trees of Indiana” by T.E. Shaw was published in 1956 as a user-friendly guide to local species.  Nearly 70 years later, the publication has been updated through a joint effort by the Purdue Department of Forestry and Natural Resources, Indiana 4-H, and the Indiana Department of Natural Resources, and reintroduced as “An Introduction to Trees of Indiana.”

The full publication is available for download for $7 in the Purdue Extension Education Store. The field guide helps identify common Indiana woodlot trees.

Each week, the Intro to Trees of Indiana web series will offer a sneak peek at one species from the book, paired with an ID That Tree video from Purdue Extension forester Lenny Farlee to help visualize each species as it stands in the woods. Threats to species health as well as also insight into the wood provided by the species, will be provided through additional resources as well as the Hardwoods of the Central Midwest exhibit of the Purdue Arboretum, if available.

This week, we introduce the honey locust or Gleditsia triacanthos.

This tree, also called “thorn-tree,” has multi-pronged thorns of two inches or more in length, which occur on the trunk as well as on the limbs and twigs. Honey locust can be found with doubly compound leaves with very small oval leaflets arranged alternately on the main leaf stem, or it can have singly compound leaves with very small leaves on a straight stem. Leaves produce a bright yellow fall color.

The bark is tight and red-brown on young trees and features gray-brown scaly strips on older trees. The fruit of the honey locust is a wavy, glossy brown flat pod that reaches lengths of between eight inches and one foot and curl or twist at maturity. These pods, which contain several seeds, are held on the tops of the trees and are highly favored by wildlife.

Honey locusts grow 70 to 80 feet tall.
