![]() ![]() Preferring full sun, Oak Trees grow easily throughout most of the United States, with many species preferring slightly acidic well-draining soils. These trees, often ranging between 40 and 80 feet tall, extend outwards in the same range, providing full shade. Oak Trees are also grown for the generous shade they provide in summer. Oak Trees grow quickly as saplings, establishing themselves within a few growing seasons as the dominant tree in most landscapes.

Hill's oak leaves turn color and are shed in the autumn. Pin oak leaves turn red or brown in the fall and persist on the tree during the winter. Whereas pin oak grows in moist, bottomland soils, Hill's oak prefers drier upland soils. The trees also differ in their habitat preferences. It is distinguished from Hill's oak by its acorns, which are shorter and covered by a shallower cup than those of Hill's oak which are about twice as long and taper.
