Willow oaks are found in much of the eastern United States and as far west as Texas and Oklahoma.They prefer stream sides and wet areas, but can also be found in upland areas. The shape of the leaves, which are long and skinny like willow-leaves, are what give this oak species its name. Willow oaks produce acorns in abundance and are an important food source for wildlife.
Willow oaks have separate male and female catkins that consist of small, inconspicuous, yellowish-green flowers. The male and female flowers can often be found on the same tree. This tree is commonly planted for shade and is often found along the edges of ponds and reservoirs.
