Japanese Snowball

Japanese Snowball is a graceful deciduous viburnum known for the rounded clusters of white flowers that cover its branches in spring. The blooms often emerge with a pale green tint before maturing to bright white, creating the appearance of snowballs resting across the shrub.

Its deeply veined green foliage adds texture throughout the growing season and may develop burgundy or reddish-purple tones in fall. The layered branching habit also gives the shrub an attractive shape after flowering ends, making it useful for adding structure to larger planting areas.

Japanese Snowball works well as a specimen shrub, flowering hedge, mixed-border plant, background shrub, or foundation planting. It can become broad and spreading as it matures, so give it enough room to develop its natural form. Avoid planting it too close to walkways, buildings, or smaller shrubs that may eventually become crowded.

Plant Japanese Snowball in full sun to part shade with moist, well-drained soil. It generally produces the strongest flowering with plenty of sunlight, although some afternoon protection may be helpful during hot Georgia summers. Water regularly during its first growing season so it can develop a strong root system.

Apply two to three inches of mulch around the root zone to conserve moisture and reduce weed growth. Keep the mulch several inches away from the main stems to prevent excess moisture from collecting around the base.

Japanese Snowball forms its flower buds on older growth, so pruning should be completed shortly after the spring flowers fade. Remove dead, damaged, weak, or crossing branches first, then lightly shape the shrub if necessary. Pruning too late in the season may remove buds that would have produced flowers the following spring.
