Description

Bur Oak are native to the Blackland Prairies of central and north Texas. Bur Oak are large stately trees with symmetrical and densely rounded crowns. 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. Bur Oak trees produce the largest acorn of any oak species that are 1 1/2 inches long and are almost completely covered with a furry cap. 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.
