Where Do Blackjack Oaks Grow?

Blackjack oaks (Quercus marilandica) are deciduous trees that are native to the eastern United States. They get their name from their dark, nearly black bark which is covered in small, sharp spines. Blackjack oaks grow in a variety of habitats but are most commonly found in dry, sandy soils. They are often found in upland areas such as hills and ridges. Blackjack oaks typically grow to be about 30 feet tall and have a spread of about 20 feet. The leaves of blackjack oaks are alternate, simple, and oblong-shaped.

PRO TIP:Blackjack oaks are native to the southeastern United States, growing in a range from Virginia to Florida and west to Texas. They typically grow in dry soils and full sun, preferring open areas with little competition from other trees.

They are dark green in color and have a smooth texture. The margins of the leaves are toothed and the tips are pointed. The leaves turn red or yellow in the fall before they are shed from the tree. Small, dark-colored acorns grow on blackjack oaks. These acorns mature in one year and are an important food source for many wildlife species including squirrels, deer, and turkey.
