In a Nutshell:
* Quercus incana is a species of oak known by the common names bluejack oak, upland willow oak, sandjack oak, and cinnamon oak. It is native to the Atlantic and Gulf coastal plains of the United States, from Virginia around Florida to Texas and inland to Oklahoma and Arkansas.
This oak is a tree growing to about 10 meters in height, with a maximum height around 15 meters. The "national champion bluejack" was a specimen from Texas that was 15.5 meters (51 feet) tall and 2.1 meters (7 feet) in circumference, and had a crown spread of 17 meters (56 feet). 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 wide. They are glossy green on top and woolly-haired underneath. The acorn is up to 1.7 centimeters long by 1.6 wide, not counting the cap. The oak reproduces by seed and by resprouting from the root crown when the upper parts are removed. It can form thickets by spreading underground runners. more...
