Description
Quercus incana is a tree growing to about 10 meters (33 feet) in height,[4] with a maximum height around 15 m (49 ft).[3] The "national champion bluejack" was a specimen from Texas that was 15.5 m (51 ft) tall and 2.1 m (7 ft) in circumference, and had a crown spread of 17 m (56 ft).[3] The trunk is short and the crooked branches form an open, irregular crown. The platy bark is dark brown or black. The leaves are generally oval and up to 10 centimeters long by 3.5 cm wide. They are glossy green on top and woolly-haired and bluish in color underneath. The name bluejack refers to this bluish and ashy appearance of the leaves.[5] The acorn is up to 1.7 cm long by 1.6 cm wide, not counting the cap. The oak reproduces by seed and by resprouting from the rootcrown when the upper parts are removed. It can form thickets by spreading underground runners.[3]
