American Hornbeam


Hornbeam leafy branch

Introduction

The American hornbeam is also known as “musclewood” because its bark has taut, shallow fissures that mimic the texture of muscle. As stout as its nickname implies, the hornbeam is able to survive in plenty of shade, which makes it a great addition to shady areas that other trees would struggle with.
