Bur Oak

Scientific name

Quercus macrocarpa


The Bur Oak is a member of the White Oak family and is the fastest growing Oak species. The Bur Oak is a large, deciduous tree often found growing to heights of 30 m at maturity. This tree features a full, broad spreading crown making it an excellent tree to plant for creating shaded areas. The leaves are simple, closely resembling the leaves of White Oak and are a shiny green colour throughout the spring and summer. Leaves change to a bright yellow-brown during the fall, prior to dropping. During the spring, tiny yellow-green flowers grow on catkins and mature into acorns in a single season, dropping in the fall. The Bur Oak is found in many forest, savanna, and prairie ecosystems with other hardwoods and conifers on a wide range of soils. This species is long-lived, with some trees living up to 300 years old. The root system of this tree is well-branched and deep, making it very drought resistant and an excellent species for land reclamation and restoration applications. Also, the Bur Oak's tolerance to pollution makes it a popular tree for planting in urban areas.
