American Hornbeam

American Hornbeam (Carpinus caroliniana)

American Hornbeam (Carpinus caroliniana), also known as Ironwood or Musclewood, is a native deciduous tree prized for its smooth, sinewy trunk, adaptable nature, and vibrant fall foliage. This understory tree is a durable and elegant choice for naturalistic gardens, woodland edges, and urban landscapes seeking native character and seasonal interest.

Distinctive Features

Carpinus caroliniana is distinguished by its muscular, fluted gray trunk that adds winter texture and form. The tree produces dense, finely serrated green leaves that turn shades of yellow, orange, and red in autumn. Its compact, rounded crown typically matures between 20 to 35 feet tall, making it suitable for smaller spaces while still providing shade and structure. Small, inconspicuous catkins appear in spring, followed by winged nutlets in fall that provide interest and support local wildlife.
