Quercus alba, commonly called white oak, is a large deciduous Missouri native tree of the white oak group. It typically occurs in dry upland slopes and ledges as well as lowland valleys and ravines throughout the State. Grows to 50-80' tall in cultivation and taller (to 100') in the wild. Pyramidal when young, but matures into a substantial tree with a wide-spreading, rounded crown. Insignificant yellowish-green flowers in separate male and female catkins appear in spring shortly after the leaves emerge. Fruits are oval acorns (to 3/4" long) with warty-scaled cups. Leaves (4-9" long) have 7 to 9 deep rounded lobes. Leaves emerge pinkish in spring, but mature to dark green. Variable fall color ranges from uninteresting browns to quality shades of dark red. White oak grows over much of eastern North America and is an important hardwood timber tree. Widely used in landscapes, but slow growth rate and large size has somewhat tempered its popularity.

Produces 1" sweet acorns that mature in a single season. The acorns are at the top of the food preference list for many wildlife species. The bark is an ashy light gray that breaks into narrow, thin flakes. As this species matures, it becomes a magnificent specimen and a conversation piece. Grows 40'-50' high with a similar spread under landscaping conditions, becoming 70'-80' high in the wild. Does best in well-drained soil and adapts to many different soil types. Grow in full sun.
