Snowball viburnum

Snowball Viburnum ‘Roseum’ (Viburnum opulus ‘Roseum’). Viburnum opulus ‘Roseum’, often called snowball viburnum, is an ornamental deciduous shrub prized for its spectacular spring flowering. This sterile selection develops a dense bushy habit, usually wider than tall with age, forming a rounded mass ideal for beds, informal hedges, and as a specimen plant. In May, large, pure white, globular inflorescences appear in abundance, resembling decorative pompoms that are very noticeable in the garden. Its bright green, three-lobed foliage takes on beautiful reddish hues in autumn, adding further seasonal interest.

To plant snowball viburnum ‘Roseum’, choose a suitable exposure: full sun to partial shade. The recommended soil is well-drained, tolerating fresh to slightly moist soils. Water the root ball before planting it and ensure that water can drain after planting. During establishment, check the moisture by hand before watering again. Spread mulch around the base, leaving the collar clear. Avoid systematic fertilizer applications without considering soil richness. In Quebec, choose a period when the ground is thawed and easy to work.

Allow a width of 3.5 m (12 ft) to plan the plant's placement in the garden. The indicated height of 3 m (10 ft) helps choose its position relative to neighboring plants. Maintain access to the base for weeding, checking moisture, and removing damaged parts. Associate this variety with plants whose light and water needs are compatible. If you are considering a container, first check that its volume and drainage are suitable for root development. Potted roots are more exposed to cold than those planted in the ground.
