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 plant is a snowball hydrangea?
The huge, spherical, white flower heads of the snowball hydrangea are its most distinctive feature. These lovely native bushes frequently cover themselves in flowers that measure 10 inches in diameter, giving them the appearance of having just been buried in snow, hence their name. But occasionally, despite having survived the winter, these hydrangeas fail to blossom in the summer after planting. Your soil, the plant’s environment, or the way you pruned your snowball hydrangea could all be the issue. Or perhaps the absence of blooms is caused by a combination of all these factors. Follow these four measures to guarantee your hydrangeas give you a stunning display every summer.
Which bush resembles snowballs?
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.
What distinguishes a snowball hydrangea from a snowball 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.
Does a snowball bush have summer-long blooms?
Different Snowball Bush varieties need different kinds of maintenance. Viburnum plicatum, the Snowball Bush’s scientific name, is also sometimes shortened to Snowball Viburnum.
Different Snowball Viburnum Types Include:
- V. burkwoodii – A smaller type that reaches a height of 10 feet and has a fragrant, spicy scent.
- The “fragrant snowball” form of V. carlcephalum is smaller and has a stronger scent.
It’s important to distinguish between snowball viburnum and hydrangea arborescens. Despite the fact that both require identical care, it’s critical to understand which kind you have.
Common Names of Snowball Viburnum Bushes Include:
- U.S. Snowball Tree
- Snowball Tree in Japanese
- The Japanese Snowball Bush is recognized for its large white blossoms and brilliant green leaves that usher in spring. It is also known for being extremely easy to grow. The snowy-white blossoms of the Snowball begin as a brilliant lime-green in late spring and gradually change to that hue by mid-May, holding onto it for a period of time.
