Arbor walk #22, Treekeeper ID #1513

Willow Oak

This large native tree has a simple, small leaf, and a finer texture than most oak trees. It is considered a medium to large oak, can grow over 100 feet tall, and is native to the Southeastern portion of the United States, including Missouri.

In Missouri, the Willow Oak is generally found in wetter areas bordering swamps. In the Oak family, this tree stands apart in that its leaves are unusual for an Oak. Instead of an Oak’s normally multi-lobed leaves, the Willow Oak has a simple, slender leaf. This tree has a rapid growth rate, growing up to 100 feet, with its acorns maturing within two years.
