The Story
Plant Bio
Viburnum plicatum var. tomentosum, or Doublefile Viburnum, is a deciduous shrub known for its distinctive horizontal branching and flat-topped clusters of lacecap flowers that create a layered, 'wedding cake' effect. 'Summer Snowflake' is a more compact cultivar that is a prolific repeat bloomer, producing flowers intermittently from late spring through to fall. It also develops attractive red fruit which ages to black.

Care Guide
Do
- Provide consistent moisture, especially in the first year
- Prune immediately after the main spring flush of flowers
- Plant another V. plicatum var. tomentosum cultivar nearby for best fruit set
Don't
- Don't prune in late summer or fall, as this will remove next year's flower buds
- Avoid letting the soil dry out completely during hot spells
- Don't plant in heavy shade, which reduces flowering
