The bark is gray-brown, deeply fissured, shaggy; branches ridged, shedding plates of bark; twigs stout, pubescent, and winged with corky ridges. The wood of a bur oak is brown, closely grained, heavy, durable with conspicuous pith rays, used as the highest grade of white oak in the lumber trade. Bur oak leaves are 6-12″ long, oval, 5 to 7 lobed. The upper surface is lustrous, dark green; lining silvery pubescent. Flowers: staminate in profuse, clustering catkins with opening leaves. Acorns are 1/2 to 2 inches long, fuzzy, in deep brown hairy cups, annually, kernels are white & sweet. Bur Oak tolerate a wide range of soils but prefers moist soils. Well-adapted to alkaline soils, poor drainage, and high clay content, Bur Oak is also very drought-tolerant. Bur Oak grows best in full sun. Bur Oak will adapt to various soils where other Oaks sometimes fail but is difficult to transplant from well-drained soil due to the tap root. Excellent lumber tree. They are native from Nova Scotia to Montana; south to Pennsylvania, Tennessee, and Texas. Bur Oaks can be difficult to transplant because of the deep taproot. The tap root dominates the root system on young trees growing in well drained soil. If you are planning to buy Bur Oaks for landscape sales we highly recommend our root growing bags for easy transplanting as the Bur Oak tap root can not penetrate the bag..
