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 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.
Snowball hydrangeas are found where?
Chinese Snowball Viburnum: In warmer locations, additional afternoon shade may be needed for this stunning plant to thrive in full sun to partial shade.
Hydrangea Annabelle: Hydrangeas generally like morning sun and afternoon shade, and Annabelle is no exception. Although its blossoms are said to be the most forgiving, still managing to put on a spring show even after a difficult winter or heavy pruning, according to online plant reseller and information source Plant Addicts Inc.
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.
Are snowball bushes contagious?
Some snowballs can reach a height of 15 feet and enjoy spreading their roots. The optimum location will receive six to eight hours of bright sunlight daily. To fit the root ball of the shrub and give the roots room to spread out, dig a hole twice as broad and as deep as the rootball.
How much height 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 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 kind of hydrangea can tolerate direct sunlight?
The majority of hydrangeas only like morning sun. The panicle hydrangea is the only variety of hydrangea that can remain in the sun all day. Although they can tolerate the sun, these also thrive in some shade. Additionally, panicle hydrangeas are the most resilient varieties.
