Description

Though Ostrya virginiana is commonly an understory tree, it will also thrive in full sun where it can reach heights of up to 50'. Mature specimens have reddish, scaly pealing bark. Catkins emerge at the same time as the new leaves. It produces nutlets contained in papery clusters resembling hops. These are attractive and persist well into winter, providing a valuable food source for wildlife. The oval serrated leaves are typical of other members of the Birch family, and turn yellow in fall.

Cultivation

Ironwood is easily grown in any light and soil condition, provided it is given proper drainage. It is drought resistant, has a shallow root system, and is intolerant of persistently wet soils. Due to its extensive native range, it may bloom as early as March in the south, and as late as June in the north. Zones 3-8

Propagation

Propagate from freshly collected seeds, that have been carefully and thoroughly removed from their papery casings. Stored seeds will do best if subjected to cold stratification.

Additional Notes

This slow growing tree can be used as an alternative to introduced elms and is well adapted to urban environments. It produces the hardest wood of any north American native tree, giving it the common name ironwood. The common name hophornbeam, is a reference to the similarities between its fruit, and hops.
