Sourwood (Oxydendrum arboreum) is a small tree or large shrub that can reach 20-30′ in cultivation (50′ in the wild) and grows naturally in well-draining clearings and woodland bluffs, ravines, and hills. It is often used as an ornamental tree in landscaping, usually as a specimen tree or in group plantings. The showy, white, bell-shaped flowers bloom on drooping panicles resembling Lily of the Valley, hence one of the common names Lily of the Valley Tree. Sourwood produces more blooms in full sun, and the nectar attracts bees, butterflies, and other native pollinators. The leaves are dark green in summer but turn a vivid bright scarlet in fall. Pale yellow fruit capsules that appear after blooms are spent contrast well with the fall color and maintain winter interest after leaves drop. The fruit provides food for birds and small mammals. Natural hollows in the tree provide refuge for climbing reptiles and amphibians, bats, and other small wildlife.
