Common Snowball Viburnum
Big, Showy White Snowballs Every Spring
Common Snowball Viburnum (Viburnum opulus 'Roseum') is the beloved old-fashioned snowball bush, smothering itself each spring in large, rounded clusters of pure white flowers that look just like snowballs hanging from the branches. The blooms open pale green and mature to white, making a spectacular show on a big, arching shrub. Tough, deer-resistant, and easy, this nostalgic favorite is a stunning specimen, screen, or backdrop in Eden Prairie, Plymouth, and Eagan.

Landscape Uses
Use Common Snowball as a dramatic spring-flowering specimen, screen, or backdrop in large borders. Its snowball blooms are excellent for cutting. Because the showy flowers are sterile it does not set fruit, keeping it tidy and seedling-free.
Best Time to Plant
Plant in spring or early fall, when cooler weather and steady moisture help roots establish.
How to Plant
Dig a hole twice as wide as the root ball and just as deep. Set the crown level with the soil, backfill, water in well, and mulch 2–3 inches deep, keeping mulch off the stems. Give it room to reach full size.
Watering
First Year: Water deeply 2–3 times per week to establish the roots.
After Year One: Water during dry spells; it prefers average to moist soil.
Drip Irrigation: A drip line or soaker hose keeps the root zone evenly moist.

Common Snowball Viburnum Season-by-Season in Minnesota
- Spring: Lime-green buds swell into big, rounded snowball clusters that mature to pure white in late spring — the signature show, and excellent for cutting.
- Summer: Clean, maple-like dark green foliage on a dense, arching shrub makes a solid green backdrop.
- Fall: Foliage can blush purplish-red in a good year; because the flowers are sterile, there are no berries to drop or stain.
- Winter: The tall, arching branch framework gives the back of the border useful structure against the snow.

Is Common Snowball Viburnum Right for Your Yard?
Choose it if you have full sun to part shade, average-to-moist soil, and room for a 10–12 ft shrub to arch naturally — it shines as a specimen, screen, or back-of-border anchor, and deer largely leave it alone. It's not a fit if you're after wildlife value or a small foundation bed: the sterile blooms feed no pollinators and set no fruit, and it's simply too large for tight spaces.
