Swamp White Oak

Arbor walk #105

This tree is in the Fragaceae family and is native to Missouri; another common name is swamp white oak. It is a deciduous tree with broad and rounded crown, which is good for shading. The leaves are dark green above with silvery-white underside. Leaves turn to golden or orange brown in fall. Mature bark is a dark gray-brown with blocky ridges. Young trees develop a flaky, peeling bark that reveals an orange inner bark. Acorns are 1 inch long and enclosed halfway with a warty cap. The cap often remains attached to a stalk (peduncle) once the fruit is ripe and falls from the tree.
