The tree gets its common name due to its resemblance to willows, specifically because of its narrow, elongated leaves bearing a shape reminiscent of willow leaves.

The willow oak is characterized by its distinctive, dark green foliage that turns to yellow or reddish-brown in the fall.

The tree produces small, oval acorns that are approximately 0.5 to 1 inch (1.3 to 2.5 cm) long, which serve as a food source for various wildlife.
These oaks are commonly found in moist, well-drained soils near streams, rivers, and other bodies of water, as they thrive in wet environments. They are also quite adaptable and can tolerate a range of soil types, including loamy, acidic, and clay soils. The willow oak is highly valued for its ornamental purposes and is often cultivated in urban areas and landscapes for its aesthetic appeal and shade-providing qualities.
Due to its strong wood, the willow oak has also been utilized in the construction industry for various purposes, such as furniture, cabinetry, and veneer production. Additionally, its acorns are consumed by some wildlife species, including squirrels, deer, and ducks, contributing to its ecological significance.
