Leaves: The leaves of White Oak are lobed and have rounded tips. They are dark green in color and turn shades of red, brown, or purple in the fall. The leaves are typically 4 to 9 inches (10 to 23 centimeters) long and have a distinctive shape with rounded lobes.

Acorns: White Oak produces acorns that are an important food source for wildlife. The acorns are oval-shaped and about 1 inch (2.5 centimeters) long. They have a cap that covers about one-third of the nut. The acorns mature in one season and are an important food source for birds, squirrels, and other animals.
