Oxydendrum arboreum, commonly known as sourwood or sorrel tree, is a deciduous tree native to the southeastern United States. Here are some key features and information about Oxydendrum arboreum:
Leaves: The leaves of sourwood are alternate, simple, and deciduous. They are oblong or lance-shaped, about 4 to 8 inches long, with finely serrated margins. In the fall, the leaves can turn striking shades of red, orange, or purple.
Flowers: Sourwood produces drooping panicles of small, urn-shaped, white flowers in mid to late summer (June to July). The flowers are fragrant and have a distinctive appearance.
Fruit: The tree develops small, dry capsules containing winged seeds. These capsules persist on the tree through the winter, adding some interest to the landscape.
Bark: The bark is gray and smooth when young, but it becomes rough and furrowed as the tree matures.
Habitat: Sourwood is typically found in acidic soils, often in the understory of mixed hardwood forests. It is well-adapted to both dry and moist soils.
Size: It is a relatively small to medium-sized tree, reaching heights of 25 to 40 feet (7.6 to 12 meters) tall.
Fall Color: One of the notable features of sourwood is its excellent fall foliage, with leaves turning vibrant colors, adding to its ornamental value.
Landscape Use: Sourwood is cultivated for its ornamental qualities and is often used in landscaping as a specimen tree or in group plantings. It is also valued for its nectar-rich flowers, which attract bees.
Honey Production: The nectar produced by sourwood flowers is used by bees to make a distinctive honey known as sourwood honey. This honey is prized for its unique flavor and is considered a high-quality, regional specialty.
