Summary

Quercus macrocarpa, commonly known as Bur Oak, is a deciduous tree native to a variety of habitats including bottomlands, floodplains, and dry upland areas in the Central and Northeastern USA and Southern Canada. It is one of the largest and most majestic oaks, capable of growing up to 30 meters (98 feet), though occasionally reaching 50 meters (160 feet) in height. The Bur Oak is notable for its massive trunk, which can be up to 3 meters (10 feet) in diameter, and its broad, spreading crown that provides dense shade. The leaves are dark green and deeply lobed, turning yellow-brown in fall. It produces large, fringed acorns that are a valuable food source for wildlife.

The Bur Oak is valued for its hardiness and adaptability to a range of urban conditions, making it a popular choice for parks, gardens, and streetscapes. It is one of the fastest-growing white oaks and is particularly tolerant of drought, poor soil, and air pollution. Its deep root system makes it less suitable for areas with shallow, compacted soil or where underground utilities may be present. In cultivation, it thrives in full sun and can handle a variety of soil moisture conditions, from slow and wet to medium and fast-draining. Despite its size, it is relatively easy to maintain once established.CC BY-SA 4.0
