Growing Viburnum

Latin Name Pronunciation: vye-burr'num 

With the possible exception of Rhododendron, no genus offers as many attractive and useful shrubs as this one. Viburnum provides just about anything you could want in a shrub, from profuse bloom to handsome foliage to colorful fruits to fall color. Growth habit varies among species: V. carlesii (Korean Spice Viburnum) and V. opulus (European Cranberry Bush) varieties are round-topped and fairly dense; V. dentatum (Arrowwood Viburnum) is large with spreading branches, V. plicatum tomentosum (Doublefile Viburnum) has tiers of horizontal branches, and V. trilobum (American Cranberry Bush) varieties are more upright.

CULTURE: Full sun (grow in partial shade in the South and warm inland areas of the West); rich, well-drained, evenly moist, and slightly acidic soil. Viburnums do not tolerate drought well. Space 5–8′ apart, depending on variety. 

GROWTH: Plants usually need 3–5 years to start blooming and fruiting. Medium growth rate of 12–24″ a year, depending on growing conditions.

SUGGESTED USE: Screening, informal hedge, native plantings, or mixed perennial and shrub borders.

PRUNING: Prune as necessary after plants bloom in spring. Be aware that pruning will reduce the fruit production of V. trilobum varieties.
