So You Think You Found an American Chestnut Tree?

This page is designed to help you distinguish among several species of the chestnut family (Castanea) commonly seen in North America. Also included are three non-chestnut species that are often confused with chestnut.

Click on the names on the right to see examples and characteristics of the common species of chestnut or chestnut look-alikes.

A good place to start is to compare American and Chinese chestnuts. Over 80% of the leaves that are sent to us each year for identification are either from Chinese chestnuts or Chinese/American hybrids, because these trees are resistant to the chestnut blight. Also compare true American chestnut with three trees often confused with chestnut: chestnut oak, beech, and horsechestnut.

TO SEND US A LEAF & TWIG SAMPLE:

Please do not email us pictures to identify!!

  1. If you think you have an American chestnut tree, send us a freshly-cut 4-6 inch twig with mature leaves attached.
  2. Press leaves between cardboard to flatten and prevent curling or crushing as it dries.
  3. To prevent mold, do not put the sample into a plastic bag. Crushed or bent leaves are much harder to analyze, as are leaves that are not freshly collected.
  4. Spring or summer is the best time to collect samples for identification purposes.
  5. Print a TREE LOCATOR FORM and include with your sample.
  6. Results can take up to 3 - 6 weeks, depending where they are analyzed. You will get your results by mail or email.
