Stewartia pseudocamellia – Japanese Stewartia

Gardeners in the south looking for small deciduous trees often think of dogwoods and redbuds, but Japanese stewartia can be an inspired choice in the garden. It is a small tree with beautiful flowers and foliage. Japanese stewartia functions well as an understory tree, flowering even in shady areas.

The scientific name is Stewartia pseudocamellia. The first time you see Japanese stewartia in the landscape the first instinct is to wonder why a camellia is blooming in summer. Pseudocamellia = ‘false camellia’. Both camellias and stewartias are in the tea family.

The flowers are refined, 2″-3″ across in single form with white petals and gold stamens. The flowers, while beautiful, are only a small part of the charm of this tree, as its value spans all four seasons.

Japanese stewartia has beautiful foliage, good fall color, and exfoliating bark, making it valuable all year in the garden.

It grows slowly to twenty to thirty feet or more and is often grown as a much smaller shrub. It flowers in summer. The foliage is reliably healthy throughout the season and the bark exfoliates, always a worthy trait in the gardening world.

Growing Japanese stewartia in the garden

Once established, Japanese stewartia needs little to no supplemental watering. It prefers well-drained soils, and does not respond well to drought when young. Can tolerate full sun but afternoon shade can be beneficial in southern gardens. Member of the tea family, so acidic pH is recommended. Flowers do not last long but come in waves.
