American Cranberrybush Viburnum

Plant Type:

DECIDUOUS SHRUBS

Viburnum opulus var. americanum ‘Wentworth’ – This large, especially fast-growing selection comports with its displays of gorgeous deep, dark red glossy fruits. It may be useful for backdrop, screening or as an element in an expansive wildlife planting/hedgerow. In containers it has been somewhat susceptible to aphids which distort the foliage we assume because of the stress of confinement in the container. 'Wentworth' is a happier and worthy shrub in the ground. It may be useful for backdrop, screening or as an element in an expansive wildlife planting/hedgerow. In containers it has been somewhat susceptible to aphids which distort the foliage. I don’t know if it is simply a more susceptible form or if it has to do with confinement in a container or is somehow not as happy in the northeastern Connecticut climate. It is a happier shrub in the ground. Any thoughts?

Genus Overview: Viburnum

Common Name: Viburnum

Viburnum. This genus is full of fantastic, multi-season garden worthy shrubs. Garden heroes. Spring flowers, often large and showy, many with heady sweet fragrance are arranged in cymes. Some smell of musk (Viburnum dilatatum) while others produce no fragrance at all. Flowers are followed with berries. If late season and autumn berries are desired then planting two of a species will ensure fruit set; for instance, Viburnum dilatatum 'Erie' and V. dilatatum 'Michael Dodge' will pollinate each other and produce fruit. Viburnum cassinoides is closely allied with V. nudum; but if the flowering times do not overlap then there will be no fruit. However, if you plant V. nudum 'Winterthur' in proximity with V. nudum var. angustifolium, 'Longwood', 'Moonshine' or 'Pink Beauty' berries will abound. Another interesting example is V. lantana which crosses with V. burejaeticum and vice versa. Any V. plicatum selection such as 'Shasta' will pollinate with all other V. plicatum selections. But if you were to plant two 'Shasta' side by side with no other V. plicatum in near proximity then your effort will be fruitless. As with almost all in the universe of plants there are exceptions. There is one viburnum which appears to be self-fruitful, Viburnum setigerum the Tea Viburnum. And on the other spectrum are two I can think of off-hand that are barren, Viburnum plicatum 'Roseum' and Viburnum plicatum 'Kern's Pink'. Oftentimes, the dwarf viburnums reamin in a juvenile state and do not produce fruit. All Viburnum of any size that do produce fruit are magnificent in the late season garden. And they feed all manner of birds. Larger, denser shrubs provide cover and nesting opportunities. Nearly all Viburnum have terrific autumn foliage colors, too. Viburnums are members of Caprifoliaceae. All prefer part to full sun and fertile soils. All are cutting grown. Many thanks to Gary Ladman of Classic Viburnums who generously set us straight regarding some of the details we had originally incorrectly lauded... ya can't know everything!
