Description: Seven-son flower was initially introduced by China in 1980 and has become quite popular in the Northeast. This plant puts on a spectacular show in autumn with its red sepal color, and in winter with its exfoliating bark which exposes a light brown underbark. Works well as an accent, in shrub borders or in groupings.
Grows 15 to 20 feet tall, 12 to 15 feet wide with shiny, pointed, drooping foliage and small, fragrant, star-shaped white flowers produced in whorls of 7 flowers (origin of name seven sons flower). Multi-stemmed and upright spreading habit with a cloud like canopy.
Grows best in moist soils and full sun but will adapt to dry, acidic soils and semi-shade. Hardy to Zone 5.
