Bur Oak
Bur oak is a very large, stately, drought tolerant shade tree. It is a slow-growing member of the white oak family with a broadly rounded crown at maturity. It has medium green, deeply lobed leaves that turn yellow, gold, and brown in the fall.
The bark of the main trunk and branches is corky and deeply furrowed, while the twigs are almost winged with deep ridges of bark. Large (up to 1 1/2 inches), fringed acorns are produced in fall.
Bur oak is more tolerant of alkaline soils than many oaks, and very drought tolerant once established. It may retain some brown leaves during winter when young. It is an excellent choice for a large, long-lived, drought-tolerant shade tree.
