How Fast Do Blackjack Oaks Grow?

Blackjack oak (Quercus marilandica) is a small, slow-growing oak tree that is native to the eastern United States. The tree gets its name from the blackjack card game, as the leaves are similar in shape to the cards. Blackjack oaks typically grow to a height of 20-30 feet and a width of 15-25 feet. The trees have a short trunk with stout, spreading branches. The bark is dark brown or black and rough textured. The leaves are simple, alternate, and obovate in shape with a pointed apex.

The margins of the leaves are serrated and the leaves are dark green in color with a paler underside. The fall foliage is yellow to reddish brown. The acorns of the blackjack oak are oval in shape and dark brown in color with a conical cap. The acorns mature in one season and are an important food source for wildlife.

Blackjack oaks are found in dry, sandy soils in open areas such as woods edges, fields, and roadsides. The trees are tolerant of drought and fire.
