Ostrya virginiana, commonly called American hop hornbeam, is a deciduous tree which usually occurs in dry soils on rocky slopes, upland woods, and bluffs. A small to medium-sized, understory tree with a generally rounded crown. It typically grows 25-40' tall with a slightly smaller spread.
A native deciduous shade tree in the Betulaceae family. The leaves look similar to and can be confused with birch trees, and its overall form can sometimes be confused with an elm tree. It has shaggy bark that provides winter interest. Eastern hophornbeam is small to medium understory tree. It is low maintenance and works well in urban settings, probably because it tolerates drought and heavy clay soils. Plant in a lawn, along a driveway, street, or in a woodland garden. It is sometimes referred to as "ironwood" because of its extremely hard and dense wood.

Female catkins are followed by drooping clusters of sac-like, seed-bearing pods which, as the common name suggests, somewhat resemble the fruit of hops and persist from summer through winter.
