The smooth hydrangea variation known as the old-fashioned snowball, or Annabelle hydrangea, is a naturally occurring form that thrives in USDA plant hardiness zones 3 or 4 through 9. It is linked to other attractive shrubs like deutzia and mock orange and is a member of the hydrangea family (Hydrangeaceae). The Chinese snowball viburnum, or Viburnum macrocephalum, is a member of the muskroot family (Adoxaceae), which includes elderberry shrubs and is hardy in USDA zones 6 through 9. Both plants are common decorative plants.
What distinguishes a hydrangea from a viburnum?
Large clusters of blooms that emerge as pale green and eventually become white are produced by the traditional snowball bush (Hydrangea arborescens), commonly known as the Anabelle hydrangea. Despite the fact that the two plants are unrelated, the Chinese snowball viburnum bush (Viburnum macrocephalum) resembles it in appearance and likewise produces flowers that start out pale green and eventually become white. If you’re unsure of how to differentiate snowball bushes, search for these traits:
- Viburnums grow to a height of 6 to 10 feet (2 to 3 meters), but snowball hydrangea shrubs only reach heights of 4 to 6 feet (1 to 2 meters). It is a viburnum if the shrub you are looking at is well over 6 feet (2 meters) tall.
- A snowball viburnum bush cannot survive in a region that is colder than USDA plant hardiness zone 6. In cooler regions, snowball shrubs are presumably hydrangeas.
- Compared to viburnums, hydrangeas have a much longer blooming season, with flowers often lingering on the bush for up to two months. Viburnums bloom throughout the summer, whereas hydrangeas bloom in the spring and can rebloom in the fall.
- Smaller flower heads on hydrangeas rarely measure more than 8 inches (20.5 cm) in diameter. The size of a viburnum flower head ranges from 20.5 to 30.5 cm (8 to 12 inches).
Both of these shrubs need light shade and moist but well-drained soil to thrive. Viburnum may survive brief periods of drought, while hydrangea is picky about its moisture.
The two bushes’ pruning techniques make a significant difference. Hydrangeas should have a severe winter pruning. This encourages them to grow again in the springtime, thick and leafy. On the other hand, viburnums require pruning as soon as the flowers stop blooming. The lovely burst of blooms for the following year can be lost if you wait too long.
What kind of flower resembles a hydrangea?
Hydrangea-like Clusters of Red Flowers Crape myrtles (Lagerstroemia indica) produce enormous, opulent clusters of flowers in the summer that resemble hydrangeas in hues of red, white, and various colors of pink and purple.
What kind of bushes resemble hydrangeas?
The hydrangea shrub, Viburnum opulus, sometimes known as the snowball bush, is similar in that it likewise produces a big, globe-shaped blossom in the middle of spring and summer. Snowball bushes, according to the “Great Plant Guide” of the American Horticultural Society, offer vivid autumn color and red berries in the fall. When fully grown, they reach a height of 15 feet and a width of 12 feet. The snowball blossom resembles it in size and form and is white. In particular, the paniculata hydrangea, which may reach heights of 10 to 22 feet and bear huge white blooms, and the snowball bush are similar. Snowball bushes prefer full light and can withstand most types of soil.
- Popular landscape plants called Hyrdrangeas generate big, spectacular flower heads.
- There are several shrubs that resemble hydrangeas and produce enormous, beautiful blooms on shrubs that are similar in size.
How is viburnum pruned?
There are numerous kinds and variants of viburnum. Generally speaking, they need relatively little pruning. Viburnums can be pruned for two purposes: first, to give the shrub shape, and second, to bring back an overgrown specimen. The precise method to be employed will partially rely on the viburnum’s species or variety and partly on why you are pruning.
All viburnums bloom on old wood, which means that the flower buds were created the year before. Therefore, pruning too late in the season will prevent the plant from producing flowers the next year. Viburnums can be softly pruned to shape right after blossoming. Cut back any branches that alter the shrub’s shape to a pair of newly grown leaves and remove the flower heads. Keep in mind that removing the flower heads will prevent the development of fruit, which in many viburnums can be very appealing.
Leave the more thorough pruning until late winter or early spring. Pruning to remove roughly a third of the branches each year is preferable to completely chopping back the shrub. Branches can be pruned to a few inches above the surface of the ground. The overall growth of the shrub will be constrained, the plant will be encouraged to replace these with new, healthy branches each year, and you will still have flowers. Remove any dead or damaged branches at the same time. This kind of trimming ought to be carried out right away following flowering on viburnums that produce winter blooms, such as Viburnum x bodnantense and V. farreri. Last but not least, any suckers that emerge throughout the growing season ought to be eliminated.
Viburnum: an evergreen or not?

When should hydrangeas be pruned?
when hydrangeas should be pruned. The majority of pruning is done in the early spring or late winter. But after summer blossoming, the climbing hydrangea is clipped.
What complements hydrangeas well?
Perennials that can tolerate the shade are perfect next to hydrangeas. Hostas, ferns, foxglove, and coral bells are a few of the best. A shady area is created behind the leaves of numerous upright hydrangeas. Hostas that prefer the shade do well in this area. Hostas are typically grown in gardens for their attractive foliage. The pale hosta flower spikes that some gardeners remove because they don’t like them will be concealed by the hydrangea leaves above.
Hostas come in a variety of green hues, from blue-green to chartreuse. Many have uniformly colored leaves, while others exhibit leaf variegation in white or yellow. Choose greenery to go with your hydrangea blossoms.
You can combine two or three different varieties, or you can utilize only one type. Around the hydrangea base, plant them in a single row in a circle or half-circle, or in small groupings in a triangle configuration. White blooms go nicely with green and white variegated hosta species, while pink hydrangea blossoms pair well with hostas that have bluish-green leaves.
Hostas come in a variety of heights and leaf widths. Even if they initially appear to be quite far apart, they tend to get bigger every year, therefore plant them where instructed on the label. Plant annuals in the voids for the first year or two if you don’t like them.
If you decide on perennials that require more sun, such as daylilies, place them next to hydrangeas, such as smooth or panicle hydrangeas, that can withstand more sun.

What kind of plant is a snowball tree?
Although they have a similar appearance, the snowball hydrangea (Hydrangea arborescens) and the snowball bush (Viburnum plicatum) are two distinct species of plants. Both are deciduous shrubs with some similarities and some differences. Native to China and Japan, snowball bushes, also known as Japanese snowball bushes, flourish in USDA plant hardiness zones 5 through 8. In USDA zones 3 through 9, the snowball hydrangea, sometimes known as smooth hydrangea, is a native of the Eastern United States.
