Yellow Birch (Betula allegheniensis)
Yellow Birch (Betula allegheniensis)
Description
Latin Name: Betula alleghaniensis
Other Common Names: Yellow Birch
Hardiness Zones: 3-7
Mature Size: Yellow Birch typically grows to a height of 60-75 ft (18-23 m) with a trunk diameter reaching approximately 3.5 ft (1 m). In open areas, the crown tends to be wide and even, whereas in dense forests with limited space, the crown is smaller and less uniform. A healthy tree can live up to 150 years (Illinois Wildflowers).
Preferred Soil and Climate: Yellow Birch thrives in full sun to part shade and prefers moist, loamy, or sandy soils. It is not well-suited to hot, dry summers and is native to northeastern North America, thriving in cooler regions (Illinois Wildflowers).
Additional Notes: The name "yellow birch" derives from the color of its bark, which ranges from yellow to bronze. The outer bark is thin and peels into papery sheets, while small branches and twigs exhibit a reddish-brown to grayish-brown color. When the inner bark is broken, it emits a slight wintergreen aroma. Leaves grow singly or in pairs on twigs, measuring 2-4 in (5-10 cm) long and 1-3 in (2-8 cm) wide, with an ovate shape and dark green upper surface. Male and female catkins grow on the same trees; male catkins form in clusters of 3 to 6 at twig tips, reaching lengths of 2-4 in (5-10 cm), with a purplish-yellow hue. Female flowers are shorter and green, developing into winged samaras (seeds) when mature (Illinois Wildflowers). Yellow Birch wood is extensively used for flooring, cabinetry, and even toothpicks, with most birch wood in North America originating from this species.
Common Issues: Yellow Birch is susceptible to various pests including caterpillars, aphids, leafhoppers, birch lace bugs, stink bugs, borers, leaf beetles, and sawflies (Illinois Wildflowers).
Wildlife: This tree primarily attracts birds and serves as shelter for mammals (Illinois Wildflowers).
