Viburnum plicatum
Easy · Beginner friendlyAbout Japanese Snowball
Japanese Snowball is a strikingly architectural deciduous shrub from Japan and China, growing 8-15 feet tall with distinctive horizontal layered branches. The form 'tomentosum' (doublefile viburnum) produces flat lacecap flower heads along the top of each horizontal tier, creating a wedding-cake effect. The snowball form produces round clusters of sterile white flowers. Dark green pleated leaves turn burgundy-red in fall. Red berries ripen to black and are devoured by birds.

History
Viburnum plicatum occurs naturally in Japan and China. Swedish botanist Carl Peter Thunberg described the species in 1784 based on the cultivated double-flowered (snowball) form that had been selected centuries earlier in Chinese and Japanese temple gardens—unaware at the time that this was an ornamental sterile form. The wild single-flowered lacecap form (var. tomentosum) was introduced later by Robert Fortune in 1865 and Carl Maximowicz described it scientifically in 1867.
The shrub's distinctive horizontal branching arrangement and two rows of lace-like white inflorescences (central fertile florets surrounded by showy sterile bracts) held erect above each branch in May creates an unparalleled architectural garden effect that 20th-century designer Beatrix Farrand called 'the most beautiful of shrubs'. The 'Mariesii' selection—made by Charles Maries in Japan in 1879—remains one of the finest. 'Shasta' and 'Summer Snowflake' are modern improvements.
Red fruits follow in late summer if cross-pollinated. Introduced from Japan in 1844. The doublefile form tomentosum, with its horizontally layered branches bearing rows of white lacecap flowers, is considered one of the most beautiful flowering shrubs in existence. The cultivar 'Mariesii' was collected by Charles Maries in Japan in 1879. 'Shasta' from the US National Arboretum has become the standard landscape variety. In Japanese gardens, it evokes snow-covered mountain tiers.
Symbolism & meaning
What It Symbolizes
Japanese Snowball is purity arranged on tiers, layer upon horizontal layer of pure white flower clusters resembling stacked drifts of fresh snow. Its strong horizontal branching makes a piece of natural architecture in the spring garden, almost too tidy to be wild. In its formal, snow-white display lies one of the great lessons in restrained, structural beauty.
- Purity — tiers of white flowers like layers of fresh snow
- Architecture — horizontal branching creates natural garden sculpture
Where the Name Comes From
The name Japanese Snowball points to Japan. 'Viburnum' is the ancient Latin name for the wayfaring tree; 'plicatum' means 'pleated' in Latin, referring to the corrugated leaf surface.
