The Story
Plant Bio
Viburnum plicatum f. tomentosum, the doublefile viburnum, is a deciduous shrub prized for its distinctive, tiered horizontal branching and profuse spring flowers. It offers multi-season interest with attractive foliage, flowers, fruit, and fall color.
'Opening Day' is a compact form with perfectly round, snowball-like flower clusters that emerge lime green and mature to a pristine white. Its tight, dense habit makes it a smaller, more manageable version of the classic snowball bush.

Care Guide
Do
- Provide consistent moisture, especially during the first year and in dry periods.
- Prune right after flowering to avoid cutting off next year's buds.
- Mulch annually with compost or shredded bark.
- Allow it space to grow into its natural, graceful shape.
Don't
- Don't plant in poorly drained or waterlogged soil.
- Avoid late-season pruning, as it will remove flower buds for the following spring.
- Do not let the soil dry out completely.
- Refrain from planting in deep shade, which will reduce flowering.
