Betula alleghaniensis

Common Names

Yellow Birch, Swamp Birch, Gray Birch, Golden Birch, Silver Birch

Summary

Yellow Birch is a large deciduous tree native to eastern North America, typically 60–75 ft tall with a broad, rounded crown and a trunk up to 2–3 ft in diameter. Distinctive bronze-brown to yellowish bark exfoliates in thin papery curls to reveal honey-gold inner bark, and leaves are simple, oval to oblong, 3–5 in long with doubly serrate margins that turn brilliant golden yellow in autumn. Monoecious with yellowish catkins in spring, it has a wintergreen scent when twigs are crushed, and wind-dispersed seeds that provide food for birds and wildlife. Slow-growing to moderate and long-lived, many specimens exceed a century in age.

In cultivation, Yellow Birch prefers cool, moist, well-drained soils with full sun to partial shade and is hardy to USDA zones 3–7; heat, drought, and soil compaction stress the tree, so consistent moisture is beneficial. Regeneration requires disturbed seedbeds and canopy openings, with seed crops typically every 2–3 years and seeds dispersed by wind. In landscapes it functions as a canopy tree in woods or as a specimen, tolerating a range of soils; wood is heavy and durable, valued for furniture and cabinetry, while sap can be tapped for syrup and inner bark used for flavoring. Wildlife benefits include seeds eaten by songbirds and moth/butterfly associations; common pests include bronze birch borer and related diseases, so protection and maintenance may be needed. Mulching helps conserve moisture, and protection from deer browse supports young growth.
