Got Nature? Blog

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 Pignut hickory or Carya glabra.

This tree is identifiable by its five-leaflet compound leaves and its small, smooth round nut with a partially open husk at the top. The pignut hickory has smaller buds and finer twigs than its cousins shagbark and mockernut hickory, and its nut is smooth and not ribbed. Its alternately held leaves are typically five leaflets, but may be seven leaflets, sometimes held on the same tree. The bark typically has long, running ridges that are medium or dark gray in color.

Pignut hickories grow to a mature height of 50-60 feet tall, but can be over 100 feet tall. They grow mostly on upland sites or in other places with good soil moisture drainage from New Hampshire west to Iowa and south to Texas and east to northern Florida except for the flood plain of the Mississippi River from Memphis south.
