Bur Oak trees have large leathery leaves that are 8 to 12 inches long and 4 to 5 inches wide with a dark green surface and lighter grayish green color underneath. Bur Oak leaves are highly variable in their shapes which contain 5 to 9 lobes of different size. The lower lobes on a Bur Oak are very small and the upper lobes are large resembling a crown. Bur Oak trees are extremely drought tolerate due to their long taproot which is why they are the dominant tree of north central Texas.

Mature bark on a Bur Oak appears light brown to gray which is highly ridged and deeply furrowed. Bur Oak trees are one of the longest lived oaks in Texas.
