When it comes to choosing the right flowering shrub for your garden, the options can feel endless. Among the most popular choices are the Snowball Bush vs the Hydrangea. While these two plants might seem similar at first glance, there are several factors that set them apart. Understanding the unique qualities of each can help you make an informed decision for your outdoor space.
How Are Snowball Bushes and Hydrangeas Similar?
It’s easy to see why people mix these two up. Both have big, round flower clusters and lush green leaves. They’re also both perennials, meaning they’ll come back year after year if you take care of them. And when it comes to maintenance, both appreciate regular watering and a little pruning to keep them looking their best.
Getting to Know the Snowball Bush

Let’s start with the snowball bush. This plant, sometimes called the snowball shrub, is famous for its round clusters of white flowers that really do look like snowballs. The leaves are a deep green, and the plant itself can grow pretty quickly if you let it. In fact, some gardeners find that their snowball bush tries to take over the whole garden if they’re not careful!
One of the coolest things about snowball bushes is how their flowers change color as they age. You might notice the blooms starting off green, turning to white, and sometimes even blushing pink as they mature. It’s like getting a whole range of colors from just one plant.
If you’re thinking about adding a snowball bush to your garden, keep in mind that they love sunlight. The more sun they get, the healthier and more vibrant they’ll be. They also appreciate a little bit of attention—regular pruning, especially at the end of winter, helps keep them in shape and encourages lots of new flowers when spring rolls around.
Size: Snowball Bushes can grow anywhere from 5 to 15 feet tall and about 6 to 12 feet wide, depending on the variety and how much space they’re given. Their fast growth makes them a great choice if you want to fill space quickly, but be sure to keep them pruned to maintain their shape. If you’re looking for a more traditional option, the Old Fashioned Snowball Viburnum is a classic choice known for its abundant, large white blooms and compact growth.
A quick tip: Because snowball bushes can grow fast, it’s a good idea to give them plenty of space and keep an eye on their size. Pruning isn’t just about looks; it helps prevent them from crowding out your other plants.

Hydrangea: The Garden Showstopper

Now, let’s talk about hydrangeas. If you’ve ever walked past a garden overflowing with big, fluffy flowers in shades of blue, pink, or white, chances are you were looking at hydrangeas. These plants are incredibly popular, and for good reason—they come in over 75 different species, and there’s a hydrangea for just about every garden style.
One thing that makes Hydrangeas stand out is their variety. Depending on the type you choose, you can get different flower shapes, colors, and sizes. Some Hydrangeas even let you play with the soil to change the color of the blooms—a fun trick for any gardener! If you’re looking for something unique, consider the Wee Bit Giddy Hydrangea, a smaller variety known for its compact size and stunning blue or pink flowers.
Hydrangeas are a bit more sensitive to cold than snowball bushes, but they’re still pretty tough. If you live somewhere with harsh winters, you can help your hydrangeas by covering the base with mulch or wood chips to keep them warm. Some gardeners even move their potted hydrangeas indoors during the coldest months, then bring them back outside when things warm up.
Size: Hydrangeas come in a variety of sizes, from compact shrubs that grow to about 3 feet tall to large, tree-like varieties that can reach up to 10 feet in height. Their spread can range from 3 to 8 feet wide, depending on the type and the care they receive. Smaller varieties, like the “Mini Penny” Hydrangea, are perfect for smaller gardens or containers, while larger varieties like “Endless Summer” can make a dramatic statement in more spacious gardens.
Pro tip: Hydrangeas like a bit of shade, especially in the afternoon. Too much hot sun can make them wilt, so try to plant them where they’ll get morning light but some protection later in the day.

Which One is Right for You?
Both the Snowball Bush and the Hydrangea can make stunning additions to your garden, but your choice depends on a few key factors:
-
Growth Rate and Size: If you’re looking for a shrub that fills in space quickly, the Snowball Bush might be your best bet. However, be prepared to maintain its size through pruning. Hydrangeas are slightly slower growing, but their versatility in size and color can be perfect for smaller or more intricate garden designs.
-
Sunlight Requirements: Snowball Bushes love full sun, making them ideal for sunny spots in your garden. Hydrangeas, on the other hand, can tolerate partial shade, making them a good option for areas that don’t get as much direct sunlight.
-
Winter Care: If you live in an area with harsh winters, the Snowball Bush’s frost tolerance might be more suitable. Hydrangeas, while beautiful, require more care during colder months to ensure they survive the winter chill.
