A Japanese snowball bush, or Viburnum plicatum, reaches a height of 10 to 15 feet and a width of 15 to 25 feet at maturity. Its leaves are 2 to 4 inches long and 1 to 2 inches across. In spring, it produces 4-inch clusters of flowers.

Most cultivars labeled as Japanese snowball bushes, including Grandiflorum and Rotundifolium, produce 1-inch white blossoms in each cluster, giving the flower clusters a snowball-like appearance. Other cultivars produce flat-topped clusters of flowers with a ring of infertile white blossoms surrounding a clump of 1/8-inch yellow-white fertile blossoms.

The Japanese snowball bush grows well in U.S. Department of Agriculture hardiness zones 4 through 8. It prefers full sun or partial sun. Once established, it grows well in moist soil and in drought conditions.
