Oxydendrum arboreum

Sourwood
Ericaceae
Deciduous, Trees

Native to eastern U.S. Beautiful flowering tree offering year-round interest. Slow to 15–30 ft. (eventually to 50 ft.) high, 20 ft. wide. Pyramidal shape with slender trunk, somewhat rounded crown, and slightly pendulous branches; creates a handsome winter silhouette. Narrow, 5 to 8-in.-long leaves look a bit like peach leaves; they are bronze tinted in early spring, rich green in summer. In fall, leaves turn orange, scarlet, or blackish purple; all colors may be present on the same tree. Vividly colored autumn leaves remain on the tree for a long time, dropping over an extended period much like the leaves of liquidambar. Tree blooms in the summer, bearing fragrant, bell-shaped creamy white flowers in 10-in.-long, drooping clusters at branch tips. In autumn, branching clusters of seed capsules extend outward and downward from branches like fingers; capsules ripen from greenish to light silvery gray and hang on late into winter.
