Styrax japonicus

Phonetic Spelling
STYE-racks juh-PON-ih-kus
Description

A deciduous flowering tree with a relatively compact habit  that can be vase-shaped when young but with low horizontal branching and a more broadly rounded crown with age.  It prefers moist, acidic well-drained soil in the full sun to partial shade.  casts light shade. This tree is moderately salt tolerant. Blooms in late spring and fruit ripens in late summer; foliage occurs on upper portion of branches and does not obscure pendulous flowers significantly; bark has irregular, interlacing orange-brown fissures which adds interest to a winter landscape; excellent for hillside or slope planting, but needs consistent moisture.  Plant near a patio, in a lawn, a border or in small groupings.  Plant it alongside a building on the northern side to protect it from strong winds and to provide a lovely dappled shade for underplantings.  It does not tolerate heat or drought very well.
