As an admirer of white flowering plants and shrubs I had to choose this beauty as my plant of the month. Sometimes known as Japanese snowball bush, this is a medium sized shrub with large fragrant flowers and multi-veined, dark green leaves.

Its very name ‘Grandiflorum’ describes the flower size - quite literally meaning large flowers. And this free-growing cultivar of viburnum certainly has large, rounded clusters of flowers, white in colour and gently perfumed.

It can be found within the gardens at Myerscough growing in the Winter and Spring Flowering Border where at this time of year it is a spectacular sight as the white flowerheads cascade through the leaves and stems of neighbouring plants.

Another cultivar of Viburnum plicatum found flowering at this time is V. plicatum ‘Mariesii’, a wonderful shrub with layers of horizontal stems bearing a profusion of white flowers in flattened heads. These have small fertile central flowers and larger sterile outer florets (as in lacecap hydrangeas). The plant which also produces rich, dark red autumn foliage can be seen growing in our Lime Tolerant and the Plant Families borders.

Viburnums make good garden plants with a range of deciduous and evergreen species and cultivars being grown for their attractive leaves, flowers and in some cases berries or autumn foliage. Clusters of flowers are white, pink-tinged or pink, and often scented, while berries can be red, yellow, black or blue. Flowering can be in winter, spring or early summer. Most are fully hardy though a few may require some shelter. Many can grow to be large shrubs (3m or more tall) so need gardens with space though can be pruned to a manageable size. They will grow in most soils in full sun or partial shade.
