"Stewartia pseudocamellia" (also "Stuartia pseudocamellia"; Japanese Stewartia or Deciduous Camellia; Japanese: ナツツバキ "natsutsubaki", "summer camellia";jaTrees and shrubs of Japan: [http://shinrin.cool.ne.jp/sub311.html natsutsubaki] .] Korean: 노각나무 "overripe cucumber tree"koKorean Forest Research Institute: [http://www.kfri.go.kr/kor/forest/forestation/trees_14.aspx?topmenu=3&menu=3&submenu=1 Korean Stewartia] .] ) is a plant species in the genus "Stewartia" in the family Theaceae, native to Japan (southern Honshū, Kyūshū, Shikoku) and Korea. It is a small to medium sized deciduous tree, growing to 10-15 m (rarely to 18 m) tallBean, W. J. (1980). "Trees and Shrubs Hardy in the British Isles" 4: 507-513. ISBN 0-7195-2428-8.] Rushforth, K.

The bark is smooth textured, exfoliating as the plants age, and has a camouflaged or mottled appearance with patterns of dull orange and green with grey mixed in. The trees are pyramidal to rounded in shape with deep green coloured foliage. Young stems have a zig-zag shape with flattened, divergent buds. The leaves are 4-12 cm long and 2.5-5 cm broad, arranged alternately on the stems with an elliptical shape and finely serrated edges. In the fall the foliage turns yellow, red or purple. The flowers are up to 8 cm wide, with five white petals with orange anthers; they are shaped like "Camellia" flowers, round and flat to somewhat cupped. They are produced in summer, generally in June until the end of August; each flower is short-lived, but many are produced that open over many weeks. The fruit is a brown capsule, triangular in shape with four or five angles, persistent on the trees but not showy.

There are two varieties:
*"Stewartia pseudocamellia" var. "japonica" Maxim. Japan. Flowers open cup-shaped.
*"Stewartia pseudocamellia" var. "koreana" (Nakai ex Rehd.) Sealy. Korea. Flowers open flat. Often treated as a separate species "S. koreana" Nakai ex Rehd., mainly in Korea.

Cultivation

"S. psuedocamellia" is an attractive ornamental tree that grows best in rich organic soils with good drainage and consistent moisture throughout the year. The trees generally require some light shade in the afternoon as they resent the hot afternoon sun, especially if dry. Plants are used as specimen plantings in shrub borders or as specimen lawn plantings with year round interest. It can be temperamental to establish and younger trees transplant best. [ [http://www.hort.uconn.edu/plants/s/stepse/stepse1.html Stewartia pseudocamellia ] ] When grown with single trunks they form taller more pyramidal shaped trees, when having multiply trunks plants tend to grow shorter and spread out wider. In the wild in Japan plants have been known to grow 18 m tall, and in cultivation it has already reached up to 15 m tall. [Tree Register of the British Isles] It was introduced into western cultivation in 1874, and has survived winters as cold as −30 °C [Dirr, M. (1983).
