:

• 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. pseudocamellia is an attractive ornamental tree that grows best in rich organic soils with good drainage and consistent moisture throughout the year. It is grown in full sun, but under hot and dry conditions it grows best in some light shade during the afternoon. It is used as a specimen planting in shrub borders or as a specimen in lawn plantings, having year round interest. It can be temperamental to establish and younger trees transplant best. When grown with single trunks they form taller more pyramidal shaped trees, when having multiple 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. It was introduced into western cultivation in 1874, and has survived winters as cold as −30 °C.
