Viburnum plicatum – Japanese Snowball

About Your New Viburnum plicatum – Japanese Snowball

Viburnum plicatum, sold as Japanese Snowball, is a deciduous shrub built around tiered horizontal branching and pleated, deeply veined leaves. White flowers sit along the upper face of each layer in spring, so the plant reads as a series of flowering shelves rather than a single mounded shape.

It is frost hardy and grows in full sun through to part shade, with light afternoon shade helping the foliage in hot inland districts. Moist, free-draining soil enriched with organic matter suits it best. Growth is moderate, and mature plants settle at 2 to 3 metres tall and 2 to 3 metres wide in cool temperate and temperate climates.

The horizontal habit reads well against paving, rendered walls and open lawn, which makes it a feature shrub for courtyards and cottage gardens or an informal screen through a mixed border. Flowering runs from September to November, and the foliage colours before leaf drop. Where a project wants seasonal structure rather than year-round bulk, this is a sound choice.

Frequently Asked Questions

About Viburnum plicatum

What is Viburnum plicatum?

Viburnum plicatum is a deciduous shrub from Japan, China and Taiwan, grown for its strongly tiered horizontal branching and white spring flowers. Two forms are commonly sold. Viburnum plicatum f. tomentosum carries flat lacecap heads with a ring of showy sterile florets, while the cultivar ‘Sterile’ produces the rounded snowball heads. Stock supplied as the species may be either.

How big does Viburnum plicatum grow?

Mature plants reach 2 to 3 metres tall and 2 to 3 metres wide, spreading as wide as they are high because of the layered branch structure. Allow the full width when siting it, as the tiers are the point of the plant and crowding them loses the effect. It rarely needs cutting back to stay in bounds.

When does Viburnum plicatum flower?

Flowering runs through spring, from about September to November depending on the district, with the display lasting several weeks. Flowers are white and open along the top of each horizontal branch. Cooler districts tend to flower a little later and hold the display longer than warm coastal gardens.

Is Viburnum plicatum evergreen or deciduous?

It is deciduous. The leaves colour through autumn and drop for winter, leaving the tiered branch framework exposed, which is one of the more attractive things about the plant in the cold months. New foliage returns in early spring, usually just ahead of or alongside the flowers.

Is Viburnum plicatum frost tolerant?

Yes, it is frost hardy and handles heavy and repeated frost without damage, which is why it performs so well in the Victorian ranges, the Adelaide Hills and the NSW tablelands. A late frost after bud break can occasionally spoil part of a season's flowering, but the plant itself is unharmed.

Does Viburnum plicatum need sun or shade?

Full sun gives the heaviest flowering and the tightest tiered habit. Part shade is fine and is the better option in hot inland gardens, where afternoon shade keeps the leaves from scorching through summer. Deep shade thins the plant out and reduces flowering, so avoid planting it under a dense canopy.

How do I care for Viburnum plicatum?

Water deeply through dry spells for the first two summers, then as needed in hot weather. Mulch to 75 millimetres, kept clear of the stems. Feed with a slow release fertiliser in early spring. Prune straight after flowering and only to remove dead or crossing wood, since hard pruning destroys the tiered form that gives the shrub its character.
