Lawn & Garden

The willow oak tree is a valuable shade tree that stands out due to its unique characteristics. Although it produces acorns, its leaves are willow-like instead of the broad, deeply-lobed leaves typically associated with oaks. This southeastern tree can grow up to 60 feet in height and has shiny, narrow, pointed leaves. In the southern part of its range, the leaves may remain partially evergreen, but generally turn yellow or reddish brown before falling in autumn.

The willow oak tree is faster growing than many other oaks and has a less deep taproot, making it easier to transplant. It thrives in full sun or light shade and requires a well-drained soil, preferably rich and acidic. The tree is widely used as a street and shade tree and is pollution-resistant, making it an excellent choice for a lawn specimen tree.

The shingle oak is a similar tree with slightly broader leaves and is considered a northern variant of the willow oak. The scientific name of the willow oak tree is Quercus phellos.
