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.
hydrangeas referred to as “snowball bushes”?
Large clusters of flowers that emerge as pale green and eventually turn white are produced by the traditional snowball bush (Hydrangea arborescens), also 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.
What does a snowball bush’s official name mean?
Every snowball bush plant has a distinctive personality all its own. Here are only four that you might think about including in your garden:
- 1. Chinese snowball bushes, also known as Viburnum macrocephalum, are notable for allowing their blossoms to open up more widely. As these plants develop, the flowers change from clumped-up “snowballs” to a flatter and more conventional appearance.
- 2. Eastern snowball bush: The Eastern or European snowball bush (Viburnum opulus ‘Roseum’) can grow so large that it is also referred to as a snowball tree. It is possibly the most popular snowball plant. It’s referred to as a guelder-rose by some.
- 3. Fragrant snowball bush: In late spring, this viburnum shrub’s white blossoms release a delightful scent. These plants also tend to be somewhat on the smaller side. Viburnum carlcephalum is the name of the plant.
- 4. The Japanese snowball bush, also known as Viburnum plicatum, has pleated green leaves that contrast with its brilliant blossoms. Both full sun and partial shade are beneficial to it.
What distinguishes a hydrangea from a snowball plant?
While there are minor variances, snowball hydrangea and snowball bush share comparable growth requirements.
Both plants require medium levels of watering, such as a deep soak every few weeks, and well-draining, nutritionally ordinary soil. While hydrangea may grow in either full sun or partial shade with more frequent watering, snowball bushes prefer partial shade. The snowball bush can withstand drought, however the hyrdrangea cannot and its leaves begin to wilt. Both plants lose leaves over the winter. In harsh winters, though, the hydrangea could also wither away to the ground. After the plant has finished flowering, snowball bushes require pruning to shape the bush or reduce its size. Late winter trimming of hydrangeas is necessary to both foster fresh, strong stem growth and to prune out weak stems.
All summer long do snowball hydrangeas bloom?
48-72 wide x 36-60 height. ‘Annabelle’ Hydrangea, a big flower with widespread appeal, brightens the shadow garden. In June and July, flowers can last up to two months, and flower heads are lovely all summer long and into the fall. Some gardeners relish a brief autumnal repeat bloom. Flowers from the variety “Annabelle” work well in dried or fresh bouquets. The garden’s vibrant flowers are accented by large, dark green foliage. On the growth from the current season, also known as new wood, plants bloom. Late winter pruning to the ground fosters the establishment of robust new stems. ‘Annabelle’ forms a shapely accent in the forest garden as it grows in a circular mound. Additionally fantastic for massing in perennial borders and mixed beds, or for naturalizing in native plantings. The hydrangea “Annabelle” has no significant pest or disease issues.
About Hydrangeas
Native to the US and Asia, hydrangea plants produce colorful flowers all summer long. There are numerous kinds, each with unique bloom colors, flower shapes, overall heights and spreads, levels of winter hardiness, and container-growability.
What exactly does it imply when it says “Blooms on old/new wood” and what does that have to do with winter?
On old wood, also known as “last year’s growth,” some hydrangeas generate buds that will eventually blossom; on fresh wood, commonly known as “this year’s growth;” and on both old and new wood, in the case of other hydrangeas. This information is particularly helpful for gardeners in colder climates who might lose parts of their hydrangea branches to breakage from heavy snow and ice or who might witness growing buds being killed off by late spring frosts.
These gardeners can miss out on hydrangea blossoms the following summer if they lose young buds and old growth branches. A further measure of assurance is to select a kind that blooms on new wood (or both types of growth), which ensures that your shrub will continue to bear flowers come summer, no matter how cold your winters and late springs are.
Similar to this, warm-climate gardeners who select hydrangea kinds that only bloom on new wood must make it a point to prune their shrubs to promote the development of new buds. Undoubtedly a straightforward chore, but one that needs to be kept in mind.
The majority of hydrangea bloom colors are closely related to the pH and mineral composition of your soil. The finest results will come from planting in containers since you can set the ideal soil conditions at planting time and get very vibrant hues. Changing the soil’s pH in a garden bed is possible, but it frequently takes more than one season to observe benefits. Smooth hydrangeas (Hydrangea arborescens), which are native, cannot have their color altered.
Flowers that range from purple to blue are produced by acid soils (those with a pH below 7), with the most acidic soils producing the bluest blooms. You can add sulfur to your soil to encourage the growth of blue hydrangea blooms, or you can mulch your plants with pine and/or cedar needles.
Pink blossoms grow in alkaline soils (with a pH above 7). Your blooms will be a darker shade of pink the more alkaline (or sweet) your soil is. Lime can be added to the area surrounding your growing space to achieve this. However, it is more challenging to make hydrangea flowers pink because most plants generally find it difficult to thrive in soils with a pH above 7.
Hydrangea Types
Regardless of their general kind, hydrangeas come in a variety of heights and bloom cycles nowadays. You can discover Panicles that do well in containers and Mopheads that bloom on fresh growth, for instance.
Mopheads:(Hydrangea macrophylla) (Hydrangea macrophylla) The most popular (and least cold-hardy) kind of hydrangea, mopheads are distinguished by its large blooms, which come in two varieties: lacecaps and pom-poms. Mophead hydrangeas are also referred to as “Bigleaf” hydrangeas because of its huge foliage, which adds a lot of greenery to the yard.
Panicle: (Hydrangea paniculata) The Panicle hydrangea is distinguished by its enormous, conical blooms and exceptional cold resistance. They can withstand more sun than other types because to their arching branches and profusion of blossoms.
Snowball vs. smooth (Hydrangea arborescens) These shrubs, also referred to as “Wild” Hydrangeas, are indigenous to the eastern US. While their color cannot be changed by altering the pH of the soil, their flowers usually turn a pale green as fall approaches.
Mountain: (Hydrangea serrata) These hydrangeas are native to the mountains of Korea and Japan where they are known as “Tea of Heaven.” They are more compact than Mopheads and have delicate lacecap blooms and thinner foliage. They are renowned for their lengthy blooming season and somewhat weeping shape.
Oakleafs:(Hydrangea quercifolia) (Hydrangea quercifolia) Oakleafs are native to the eastern and southeastern US and feature deeply lobed leaves that change significantly in color in the fall. With gorgeous, elongated blooms, it is extremely cold hardy.
Are snowball hydrangea and Annabelle the same?
Popular ornamental plant with lots of flowers, snowball viburnum. This plant is prized for its snowball-like circular clusters of white flowers that enchant both adults and children. Its leaves change to vivid reds in the fall.
Although it makes a good privacy screen or single accent shrub, snowball viburnum may also grow into a thick hedge.
A cold-tolerant shrub called Annabelle Hydrangea is well recognized for its massive, dense clusters of white flowers. In contrast to most floral species, hydrangeas thrive in some shade. They may, however, grow in direct sunlight if the soil is continually moist.
Regular trimming in the late winter is suggested since blooms grow on fresh wood. Try using Annabelle Hydrangea alone or as a border.

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 requirements vary, and some are time-critical. For instance, viburnum needs little frequent pruning, whilst Annabelle only needs annual renewal trimming to be clean and prolific.
