Most of the species are native to eastern [[Asia]], with two (''S. malacodendron, S. ovata'') in southeast [[North America]].<ref name="bean"/><ref name="li et al.">Li, J., Del Tredici, P., Yang, S., & Donoghue, M. J. (2002). They are [[shrub]]s and [[tree]]s, 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,<ref name="li et al."/> but others retain them within ''Stewartia''.<ref name="kew"/><ref name="china">''Flora of China'' [http://web.archive.org/web/20040814114055/http://flora.huh.harvard.edu/china/mss/volume12/Theaceae-CAS_edited.htm draft account of Theaceae]</ref> 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 [[leaf|leaves]] are alternately arranged, simple, serrated, usually glossy, and 3-14 cm long. The [[flower]]s 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 [[seed]]s in each section.<ref name="bean"/><ref name="rushforth"/><ref name="china"/> The species are adapted to [[acid]]ic [[soil]]s, and do not grow well on [[chalk]] or other [[calcium]]-rich soils. They also have a high [[rain]]fall requirement and will not tolerate [[drought]].<ref name="bean"/> Several species of ''Stewartia'' are grown as [[ornamental plant]]s for their very decorative smooth orange bark and their flowers produced at a time of year when few other trees are in flower.<ref name="bean"/> {{Inc| Stewartia (in honor of John Stuart, Earl of Bute, a patron of botany; 1713-1792). Sometimes spelled Stuartia. Ternstroemiaceae. Ornamental woody plants chiefly grown for their large and showy flowers. Deciduous shrubs or trees with smooth flaky bark: lvs. alternate, short-petioled, serrate: fls. axillary or subterminal, short-stalked, with 1 or 2 bracts below the calyx; sepals and petals 5 or sometimes 6, the latter obovate to almost orbicular, usually concave, with crenulate margin, connate at the base with each other and with the numerous stamens; styles 5, distinct or connate: fr. a woody, usually hirsute caps., loculicidally dehiscent into 5 valves; seeds 1-4 in each locule, compressed, usually narrowly winged.—Six species in E. N. Amer. and E. Asia. The stewartias are very desirable ornamental plants, with handsome bright green, rather large foliage which turns deep vinous red or orange and scarlet in fall; they are very attractive in midsummer with their white cup-shaped flowers, which are in size hardly surpassed by any others of our hardier shrubs. S. pentagyna and S. Pseudo-Camellia are hardy as far north as Massachusetts, while S. Malachodendron is tender north of Washington, D. C. They thrive best in deep, rich, moderately moist and porous soil, preferring a mixture of peat and loam, and, at least in more northern regions, a warm, sunny position. Propagation is by seeds sown soon after maturity and by layers; also by cuttings of half-ripened or almost ripened wood in late summer under glass. {{SCH}} }} ==Cultivation== ===Propagation=== ===Pests and diseases=== ==Species== ''Stewartia calcicola''<br/> ''Stewartia cordifolia''<br/> ''Stewartia crassifolia''<br/> ''Stewartia densivillosa''<br/> ''Stewartia koreana''<br/> ''Stewartia laotica''<br/> ''[[Stewartia malacodendron]]''<br/> ''Stewartia medogensis''<br/> ''Stewartia micrantha''<br/> ''[[Stewartia monadelpha]]''<br/> ''Stewartia obovata''<br/> ''[[Stewartia ovata]]''<br/> ''[[Stewartia pseudocamellia]]''<br/> ''[[Stewartia pteropetiolata]]''<br/> ''Stewartia rostrata''<br/> ''Stewartia rubiginosa''<br/> ''Stewartia serrata''<br/> ''Stewartia sichuanensis''<br/> ''[[Stewartia sinensis]]''<br/> ''Stewartia sinii''<br/> ''Stewartia villosa'' ==Gallery== <gallery perrow=5> Image:Upload.png| photo 1 Image:Upload.png| photo 2 Image:Upload.png| photo 3 </gallery> ==References== <references/> <!--- xxxxx *Flora: The Gardener's Bible, by Sean Hogan.
