STYRAX: Japanese Snowbell

Styrax japonica

Japanese Snowbell Styrax japonica

Native to China & Japan – Perfect white bell-shape flowers with light fragrance nod gracefully along the branches in May. Dark green leaves about 2” long turn yellow before dropping in autumn. Decorative green fruit follows flowers into summer. The overall shape is upright and pyramidal with horizontal side branches, making a nice canopy.

Grows 15-25’ tall & wide, sun-part shade, Z5. (Photo credit: Oregon State University)


The following are cultivated varieties of Japanese Snowbell.

Styrax 'Carillon'

Carillon

Weeping form of Japanese Snowbell with white flowers and somewhat stiff branching creating a broad shrubby shape. Grows to 8-10’ tall & wide, sun-part shade, Z5


Styrax 'Emerald Pagoda'

Emerald Pagoda

Everything about ‘Emerald Pagoda’ is bigger than the species. Bigger white flowers, thicker stems, fatter leaves, faster more upright growth. Sadly it loses some of its grace in all of that beefiness, but we still like it.

Grows to 25-30’ tall & wide, sun-part shade, Z5


Styrax 'Pink Chimes'

Pink Chimes

Pale pink flowers in May and the same thick green leaves and graceful appearance of its species.

Grows to 15-25’ tall & wide, sun-part shade, Z5


Styrax obassia

Fragrant Snowbell Styrax obassia

Native to Japan – Intensely fragrant delicate white bell flowers in 4-8 inch chains (racemes) bloom in May-June. Dark green leaves are round and larger than those of S. japonica, somewhat covering flowers. It contributes no real fall color, but the scent in spring makes up for it completely.

Grows 20-30’ tall, 15-20’ wide in a pyramid shape when young, broadening with age. Sun-part shade, Z6.
