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.
A snowball is what kind of Hydrangea, exactly?
Consider carefully where to plant a snowball hydrangea (Hydrangea arborescens), also known as a smooth hydrangea, if you recently bought one. Make careful to plant this hydrangea where it will have enough space to grow to its full size as it will reach a height of three to five feet. Although it may grow in a wide range of soil types, this plant thrives in rich, well-drained soil that is kept constantly moist. Keep your newly planted snowball hydrangea thoroughly watered for the duration of the first year while it establishes itself. This shrub flowers most effectively in dappled shade throughout the day or early sun and afternoon shade. It blooms better the more morning sunlight it receives. The leaves, however, can be scorched by a strong afternoon sun.
Are hydrangea and snowball bushes the same thing?
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.
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.
A snowball bush, does it reappear every year?
When mature Chinese viburnum flowers form primarily on the upper section of the shrub, remove older limbs. To rejuvenate the shrub, prune one to three of the oldest branches back to the ground. If your smooth-leaf hydrangeas are overgrown, you can revive them by cutting up to one-third of the old stems to the ground. Use renewal only on overgrown or bloom-less plants because it may impact the following year’s bloom.
Tip
Snowball bushes like H. macrophylla, H. paniculata, and V. macrocephalum react to total renewal by cutting the shrub to the ground, but it could take more than one season before they start blooming heavily again. If pruned to the ground in the winter, annabels will blossom as usual. Viburnums and hydrangeas will sucker, or send up new branches, in response to severe trimming. If you wish to stop the spread of your snowball shrub, trim these back as soon as they appear. Before cutting branches and after finishing each plant, sterilize cutting implements with a 10 percent solution of household bleach and water or isopropyl (rubbing) alcohol.
Warning
Before pruning, locate existing snowball bush shrubs and finish pruning at the appropriate time. Annual pruning demands differ, are time-sensitive, and come in several forms: Viburnum, for instance, requires little frequent pruning, whilst Annabelle just needs annual renewal trimming to remain clean and prolific.

What size can a snowball bush reach?
Snowball bushes, also known as snowball bush viburnums, are blooming shrubs with bushy, variegated blooms and dark green foliage. The plant gets its popular name from the shape of its spherical, clumping flowers, which remind people of snowballs. These shrubs can be deciduous, semi-deciduous, or evergreen, depending on the species. Despite looking similar, they are unrelated to the Hydrangea arborescens plant.
Snowball bush blossoms often begin green, turn white when they are fully mature, then take on a pinkish tinge as they fade. In the fall, their emerald green foliage changes to a burgundy hue. They can grow to the size of a small tree when fully grown (around twelve to fifteen feet). All cultivars or hybrids of the Viburnum opulus plant are known as snowball bushes. Snowball bushes can’t be grown from seed since they need a lot of cross-pollination and human assistance to thrive in nurseries. But once they start to grow, they’re pretty simple to spread.
How Far Apart Should Snowball Bushes Be Planted?
If you’re planting bushes in a row, leave at least 12 feet between them, and keep them clipped. It is recommended to grow snowball bushes in areas that are at least three times as wide as they are tall. Viburnum macrocephalum Snowball Bushes can reach heights of up to 20 feet in each direction when fully grown. Their branches emerge from the middle of the plant.
Can You Start a Snowball Bush from a Cutting?
If your Snowball is already fully grown, you can expand your planting by taking cuttings from a strong plant. Check for soft wood by touching certain branches. Sharp pruning shears can be used to cut off the branch if it bends before splitting into two, then it can be planted stem-down to create new bushes.
When to Plant Your Snowball Bush
Knowing the optimal times to plan helps you anticipate what will happen whether you are planting a mature Snowball Bush, using cuttings, or transplanting a sapling.
Depending on the variety of the bush, its age, and your hardiness zone, the best time to plant a Snowball Bush is either in the fall or the spring.
How to Prune a Snowball Bush
The finest methods for pruning a snowball bush depend on the kind of snowball you have and the purpose of the pruning. As a deciduous shrub, the Snowball Viburnum loses its leaves in the fall and develops blossoms on old wood.
After it starts blooming in the spring and you want to teach your Snowball Viburnum Shrub to produce plenty of blooms, cut it down to encourage additional development. Cut down one-third of the canes in the fall to thin out the base if, on the other hand, the branches have grown too long and you’re more concerned with forming a mature bush.
How much time does a snowball shrub need to bloom?
Like lilacs, snowball bushes have their own season. In the late spring, ours will bloom for about three weeks.
Our Vibernum opulus roseum is beginning to create its green blossoms at the same time the lilacs are in full bloom. In our growing zone, this takes place just around the end of May.
The blooms reached their height in mid-June and then vanished within a week.
There is no proof that the bush had any blooms towards the end of August. There are no berries with seeds to allow the plant to propagate because it is sterile.
Although none of the leaves have yet changed color, we are expecting for some stunning fall foliage.
What exactly resembles a snowball bush?
Chinese Snowball Viburnum: This plant blooms in the spring, with lime-green flowers that eventually turn white. The enormous shrub grows to heights of 12 to 20 feet, with each bloom cluster measuring around 6 to 8 inches in diameter. It goes without saying that you shouldn’t overdo it when planting. Depending on the size of your yard, you only need one or two shrubs to create a statement.
The Annabelle Hydrangea has enormous, white flower clusters that can measure up to a whopping 10 inches in diameter, and it will grow to a height and width of 4 feet. In a manner akin to the Chinese snowball viburnum, the blossoms emerge green and eventually turn white.
Do hydrangeas turn blue from rusty nails?
In reality, the presence or absence of a rusted nail or other rusting metal in the soil has no effect on how colored hydrangeas are. Many hydrangeas can transform from pink to blue without rusty nails being buried in the plant’s roots.
