Oxydendrum arboreum

Leaves are simple, alternate, deciduous and finely toothed with stiff hairs on the midrib and a sour taste. Twigs are zigzag and green to red, yellow, or brown. Buds are embedded. Bark is dark gray to black, blocky, and deeply grooved with red-orange bark inside the grooves. Flowers are white and bell-shaped forming drooping graceful clusters. Fruit is a capsule found in drooping clusters that persist into winter. Form is up to 24 m (80 ft) in height and 61 cm (2 ft) in diameter, and the trunk is often curved. Sourwood is found on a variety of sites in the eastern US. Shade tolerant. The hard wood is used for pulp and specialty items. Bees like the flowers (sourwood honey).
