Snowball bush produces enormous, perfectly round flower clusters that look exactly like their namesake, weighing down its branches with white (or lime-green, depending on variety) spring blooms.
A viburnum relative long grown in cottage gardens, snowball bush has an old-fashioned charm that's made it a passalong favorite for generations — many gardeners inherit a start from a parent's or grandparent's yard.
Snowball bush wants full sun to partial shade and well-draining, humus-rich soil. Its heavy flower clusters mean the branches benefit from a bit of support in windy spots, and pruning right after the spring bloom preserves next year's flower buds.
Snowball bush's blooms are excellent for cutting — bring branches indoors as they're just starting to open for a display that will last a week or more in a vase.
