Sourwood (Oxydendrum arboreum) is a deciduous flowering tree known for its narrow vertical structure, glossy foliage, and cascading white flower clusters. The leaves are elongated and finely serrated, creating a refined canopy that transforms into vivid autumn coloration later in the season. During bloom periods, drooping panicles of bell-shaped white flowers hang beneath the branches, giving the tree a soft layered appearance.

Native to the eastern United States, Oxydendrum arboreum naturally inhabits acidic woodland slopes and mountain forests. The species is biologically notable for nectar-rich flowers highly valued by pollinators and honey production. In mature form, the tree emphasizes vertical elegance, pendulous floral movement, and strong seasonal transformation, creating one of the most refined flowering woodland trees of eastern North America.
