General tree description

Quercus rubra is a fast-growing tree, typically reaching about 25 metres tall in open ground, though much higher in forests in its native habitat. When mature it has a broad round-topped crown. It has large oblong-ovate leaves, 10 to 25 cm long, 10 to 15 cm broad, with seven to eleven lobes. They are dark green and smooth, turning red in autumn. The acorns ripen after two years and are egg-shaped, up to 2.5 cm long.
