It is a very large, irregularly rounded tree that is covered in leathery, dark green lobed foliage for the majority of the growing season before turning an undistinguished mix of yellows and browns. Bur oaks also have very attractive, fissured grey bark that adds texture to the landscape. Acorns are abundant in maturity (takes up to 35 years to start producing) and are an excellent source of food for wildlife. Bur oaks do best in moist, well-drained soils in full sun, however they tolerate drought, clay, dry soils, poor drainage, and varied soil pH's. A very durable and long-lived tree. Quercus macrocarpa is an Iowa native. Show more
