Outstanding Features of Viburnum opulus 'Sterile'

Viburnum opulus sterile snowball comes alive each spring with masses of large, pure white flower clusters resembling snowballs. These blooms open lime green before softening to snow-white, creating a captivating multi-tone effect. The lush, dark green foliage emerges early and provides summer shelter for birds and pollinators. Come autumn, the leaves often turn shades of plum and red, adding further interest. As a sterile selection, this viburnum won’t develop berries, making it suitable for gardens where seed spread is a concern.

Ideal Growing Conditions

Viburnum opulus sterile snowball is a hearty and adaptable shrub, thriving in most well-drained soils. Choose a planting position in full sun or part shade for best flowering. Its cold tolerance makes it an excellent option for exposed sites throughout New Zealand, while regular moisture through the growing season encourages the most impressive blooms. This viburnum responds well to pruning—simply trim after flowering to shape and maintain size.
