Report an issue with this species

The American hophornbeam is a small to medium-sized, slow-growing deciduous tree native to eastern North America, known for its extremely dense wood and distinctive clusters of nutlet fruit. It thrives in well-drained soils and its leaves turn bright orange in fall, providing wildlife value by attracting birds and squirrels. This species is often found on rocky cliffs or as an understory tree in forests.
