This is the second segment of our Ornamental Tree and Shrub Series….

Who wouldn’t like a tree with the moniker “muscle wood”? Also commonly called “blue beech” or “ironwood”, the American Hornbeam is a medium-sized native hardwood tree that, on average, reaches 20 to 30 feet in height and width. Ironwood has a range from Nova Scotia through most of the eastern seaboard of the US, to include the topmost section of Florida, and westward to roughly the middle of the central time zone. It is hardy in zones 3 – 9.

The young bark is smooth and the subtly twisted trunk looks rather sinewy. As it ages the bark becomes fissured and fluted. The form can range from a multistemmed shrub to a single stemmed tree. The growth rate is slow – about a foot per year. Enjoying moisture places it along brooks predominately in the wild. This is a tree for the understory! It is tolerant of deep shade, but also will perform in full sun with a good deep acid soil and promise of adequate fertilizer and moisture. It is also a fine tree for naturalizing.

The leaves resemble that of beech. It is a simple leaf 3 – 4” long with sharp teeth. Fall color is exceptional, displaying red, maroon, orange and gold. The tree exhibits both male and female flowers that are lovely in display, and the resulting fruits are numerous nutlets prized by birds.

Carpinius caroliniana is one of my most favorite trees, even though I know I tend to say this many times about many trees. But, this understory specimen amid taller limbed up trees is a true delight in the fall that will yield wildlife activity further along in the season. I have seen an absolutely sublime alley made of American Hornbeam – the medium texture was kind on the eye and the fall display was robust.
