The pin oak (Quercus palustris) is a small- to medium-sized tree (80 ft) with a characteristic branching pattern: upper branches project upward, middle branches project straight out and lower branches project downward. The tree is deciduous and the leaves grow alternately on the twigs. The leaves are deeply and widely lobed; the underside of the leaf is lighter with hairs along the mid-vein. The autumn leaf is bright red. The flowers are male and female catkins. The fruit is an acorn with a shallow tightly scaled cup. The tree is native to the eastern part of North America and is perhaps the most popular commercial oak, having been widely planted as both a street and landscape tree.
