Description 6
More info for the term: tree
Bluejack oak is a native, deciduous small tree, usually growing to 35
feet (10.6 m), with a maximum height of about 50 feet (15 m) [11,40].
The crown is open and irregular, the trunk is usually short [15], and
the branches are stout and crooked [40]. On the Coastal Plain of
Florida, bluejack oak roots were concentrated in the top 5 inches (13
cm) of soil; this may have been related to the low fertility of deeper
soil horizons in this habitat. A deep root system is normal for most
oaks [1]. The acorns are 0.4 to 0.72 inch (10-18 mm) broad; the
involucre covers one-half to one-third of the acorn [11].
The national champion bluejack oak was reported from Texas; it measured
51 feet (15.5 m) in height, 7 feet (2.1 m) in circumference, and had a
crown spread of 56 feet (17 m) [15].
