Viburnums are a large and varied group of shrubs that range in size from two to 20 feet in height. Some viburnum species are grown primarily for their showy and often fragrant flowers, attractive fruit or fall foliage color. Some of these shrubs do not bloom or produce fruit, but produce attractive summer foliage and fall color.
Perhaps the most well-known viburnum is the old-fashioned snowball bush. This one has white flowers in late May. It is sterile and does not produce fruit.It can become pretty large- 15 to 20 feet -and is very prone to aphids, which distort the leaves. A few other viburnums are commonly grown alongColorado's Front Range.
American and European cranberrybushes grow eight to 10 feet tall. They produce white flowers and cranberry-like fruit. European cranberrybush is more susceptible to aphid than American cranberrybush.
