Stewartia (sometimes spelled Stuartia) is a genus of 8-20 species of flowering plants in the family Theaceae, related to Camellia. Most of the species are native to eastern Asia in China, Japan, Korea, Laos, Myanmar, Thailand, and Vietnam, with two (S. malacodendron, S. ovata) in southeast North America, from Virginia and Kentucky south to Florida and Louisiana.
They are shrubs and trees, mostly deciduous, though some species (e.g. S. pteropetiolata) are evergreen; the evergreen species form a genetically distinct group and are split into a separate genus Hartia by some botanists, but others retain them within Stewartia. The Asian species include both shrubs and trees, growing to 3-20 m tall, while the American species are shrubs growing 3-5 m tall, rarely becoming small trees. The bark is very distinctive, smooth orange to yellow-brown, peeling in fine flakes. The leaves are alternately arranged, simple, serrated, usually glossy, and 3-14 cm long. The flowers are large and conspicuous, 3-11 cm diameter, with 5 (occasionally 6-8) white petals; flowering is in mid to late summer. The fruit is a dry five-valved capsule, with one to four seeds in each section.
