The Story
Plant Bio
A large, deciduous to semi-evergreen shrub renowned for its enormous, spherical flower clusters composed entirely of sterile florets. It does not produce fruit. This viburnum produces some of the largest flower heads in the genus, up to 8 inches across, resembling giant snowballs. The blooms emerge lime green and mature to a brilliant pure white.

Planting
How to Grow
- Choose a site with full sun or light afternoon shade.
- Plant in fertile, moist, but well-drained soil.
- Dig a hole twice as wide as the root ball.
- Set the plant so its crown is level with the surrounding soil.
- Backfill with amended soil and water deeply.
- Mulch around the base to conserve moisture and regulate soil temperature.
Pro Tip
Provide consistent moisture, especially during dry periods, to ensure the largest, most spectacular flower heads and prevent premature wilting of the blooms.
Keep It Thriving
Care Guide
Do
- Water regularly, especially during establishment and dry weather.
- Plant in a location with good air circulation.
- Prune right after flowering to maintain size and shape.
- Provide a layer of mulch to keep roots cool and moist.
Don't
- Do not let the soil dry out completely, as this will stress the plant.
- Avoid planting in heavy, waterlogged soil.
- Don't prune late in the season, or you will remove next year's flower buds.
- Avoid locations with harsh, reflected heat from pavement or walls.
