Betulaceae

Ostrya virginiana: American Hophornbeam

Edward F. Gilman and Dennis G. Watson

This shade-tolerant tree slowly grows to 50 feet in height with a 25 to 30-foot spread but is often 25 to 40 feet tall, forming an oval or round canopy. Hophornbeam has a lovely yellow fall color, and the small nutlets, which ripen in summer and fall, are used by birds and mammals during the winter. Bark is an attractive orange or grayish brown peeling off in longitudinal strips. The finely-textured crown casts a medium or dense shade in full sun, but is more open in the shade casting a light shadow.
