Bur Oak

Quercus macrocarpa (Fagaceae) is a massive deciduous tree native to eastern and central North America from Nova Scotia to Manitoba and south to Texas. It grows 70 to 80 feet tall with a broad, rounded crown and thick, corky bark. The acorn cups are the largest of any North American oak, with distinctive fringed scales that nearly enclose the nut (the species name means "large fruit").

Bur oak is one of the most adaptable native oaks, tolerating a wide range of soil types (including alkaline), drought, cold, and urban conditions. It grows in full sun. The deep root system makes it exceptionally wind-firm and drought tolerant. The species extends further into the Great Plains than most eastern oaks. Hardy in Zones 3a to 8b.
