Distribution: North America, from central Maine to southern Quebec, southern Ontario, northern Iowa, Missouri, eastern Oklahoma, eastern Texas, and east to central Florida. Northeastern Mexico (Tamaulipas) and from southern Mexico to Guatemala and Honduras.
The Tree: The American hornbeam is a small tree that can reach a height of 13–26 ft (4–8 m), with a diameter of 4–12 inches (10–30 cm) that grows in mixed deciduous forests in the shade of taller hardwoods in bottom lands and river margins. It grows in association with oaks, sweetgum, hickories, maple and basswood. The tree grows slowly and is short lived. It masts every 3 to 5 years, producing large amounts of seed. Imperfect flowers are produced on separate catkins on the same tree.
General Wood Characteristics: The tree’s name (horn=tough and beam~baum=tree) describes the wood, which is tough, hard and heavy. Colonial settlers in America used hornbeam for bowls and dishes because it rarely split or cracked. Hornbeam has a thick, nearly white sapwood and a heartwood that is pale yellow to tan. It has no characteristic odor or taste. The wood is heavy and hard.
