Oxydendrum arboreum

Illustration of Sourwood (Oxydendrum arboreum)

Sourwood is a small to medium native tree of the Appalachian Mountains and adjacent areas, celebrated for two things: its drooping clusters of fragrant white bell-shaped flowers in midsummer, which attract bees and produce Sourwood honey — considered among the finest honeys in the world — and its spectacular scarlet and crimson fall foliage, among the earliest and most vivid of any eastern tree. Its acidic, strap-shaped leaves give it the name Sourwood. It grows on dry, acidic mountain slopes and ridges throughout the central and southern Appalachians.

Habitat
Dry acidic mountain slopes, ridges, upland forests of Appalachians
Diet
Flowers provide outstanding nectar for honeybees and native bees; small capsules eaten by birds
