Black Oak

Description:

In the northern part of its range, black oak is a relatively small tree, reaching a height of 20–25 m (65–80 ft) and a diameter of 90 cm (35 in), but it grows larger in the south and center of its range, where heights of up to 42 m (140 ft) are known. Black oak is well known to readily hybridize with other members of the red oak (Quercus sect. Lobatae) group of oaks being one parent in at least a dozen different named hybrids.
