Sourwood, scientifically known as Oxydendrum arboreum, is a small to medium-sized deciduous tree native to the eastern United States. It is also commonly referred to as the Sorrel Tree. Here’s some information about the Sourwood tree:
- Appearance: Sourwood is known for its attractive foliage and unique form. It typically grows to a height of 25-50 feet (7.6-15 meters) and has a spread of 20-35 feet (6-10.7 meters). The tree has a narrow, pyramidal shape when young, but matures into a more rounded or irregular form. The leaves are elongated, glossy, and turn vibrant shades of red, orange, and purple in the fall.
- Growing Conditions: Sourwood thrives in full sun to partial shade. It prefers acidic, well-drained soil but can tolerate a range of soil types, including sandy or clay soils. It is relatively drought-tolerant once established but benefits from regular watering during dry periods, especially when young.
