Oxydendrum arboreum, commonly known as Sourwood, is a striking deciduous tree native to the eastern United States, renowned for its stunning seasonal color and unique foliage. This tree features glossy, dark green leaves that turn a vibrant red, purple, or orange in the fall, creating a spectacular display of autumnal color. In summer, it produces clusters of small, fragrant white to pale pink flowers that attract bees and butterflies.
Sourwood prefers full sun to partial shade and thrives in moist, well-drained, acidic soils. It is relatively low-maintenance, though it benefits from regular watering during dry periods to maintain its lush appearance. The tree's tolerance for a range of soil types, including sandy and clay soils, makes it a versatile addition to many landscapes.
Ecologically, Oxydendrum arboreum supports local wildlife by providing nectar for pollinators and a rich source of food for various birds. The summer blooms are particularly attractive to bees and butterflies, while the fall foliage provides visual interest and habitat for wildlife.
In landscaping, Sourwood is valued for its year-round appeal. Its unique flower clusters and brilliant fall color make it a standout specimen tree in both residential and larger garden settings. It works well in naturalized areas, woodland gardens, and as an accent tree in mixed borders. By incorporating Oxydendrum arboreum into your landscape, you can enjoy its dynamic seasonal changes, support local pollinators, and enhance the ecological diversity of your garden.
