The trees grow in zones five through eight in full sun to part shade and prefer well-drained soil. Established plants are drought-resistant and hardy in most soil conditions.
The Water x Cherrybark oak hybrid, Quercus nigra x pagoda, is a red oak, which grows up to 100 feet tall and is an abundant producer of acorns. These acorns drop in October and November and attract wildlife, such as wild turkey, squirrels, blue jays and deer. The tree grows in zones six through nine and prefers slightly acidic, well-drained soil.
The Compton oak hybrid, Quercus x comptoniae, is a cross between the Live and Overcup oaks. The Compton oak is a faster grower, reaching up to 80 feet and produces more acorns over longer periods than either of its parents.
