Overview
Willow Oak (Quercus phellos) is a deciduous tree native to the southeastern United States, including Alabama, Arkansas, Delaware, District of Columbia, Florida, Georgia, Illinois, Kentucky, Louisiana, Maryland, Mississippi, Missouri, New Jersey, New York, North Carolina, Oklahoma, Pennsylvania, South Carolina, Tennessee, Texas, and Virginia. This tree thrives in hardiness zones 5-9 and prefers full sun to partial shade, with a preference for moist, medium to heavy (clay) soil with a pH between 4.5 and 6.5. Willow Oak is notable for its ornamental value, as well as its edible seeds, which can be used to make coffee. Traditionally, the bark has been used in Native American medicine to support immune health, with a decoction potentially helping to bolster the body's defenses against common ailments. While the tree is adaptable to various environments within its native range, it is important to use caution when considering any medicinal applications, as these should be discussed with a healthcare professional.
