Viburnum opulus, also known as European cranberrybush or Guelder Rose, is famous for producing clusters of white flowers that resemble snowballs. Some people mention it as a tree with white flowers that look like hydrangeas.
I agree with them because its striking beauty, especially in the spring and fall reminds me of the Hydrangea. I love Viburnum opulus in spring when its incredible flowers attract pollinators, have a delightful fragrance, and create a stunning display in every garden and landscape.
However, people call it a tree with white flowers that look like hydrangeas, I think the European cranberrybush has more advantages than Hydrangea for my garden. For example, in the fall, Viburnum opulus is still lovely when its foliage transforms into vibrant shades of red and orange and tells us the beautiful fall is coming. It provides a colourful backdrop in the garden, I love Guelder Rose!
Its warm colouring foliage is not the only beauty of Viburnum opulus at the end of the season, it also produces bright red berries that are visually appealing and invite lovely birds into my garden. I believe that its rounded shape and dense growth make it an excellent choice for hedges or as a focal point in gardens.
Anyway, Viburnum opulus isn’t the only plant that is similar to Hydrangea, I discussed them in my other post and you can find them there. In addition, if you are interested in planting cheaper alternatives to Hydrangea, I also have suggestions in my other post.
In this post, I will show you how to identify Viburnum opulus and distinguish it from Hydrangea, I also will give you tips for caring for it and help you to choose the best place to plant it in your garden. So, don’t waste time and let’s start.

Overall, Viburnum opulus is appreciated for its ornamental qualities throughout the year, from lush foliage to beautiful flowers and berries.
How to Distinguish Between Viburnum opulus and Hydrangea
Distinguishing Viburnum opulus from Hydrangea involves observing several key characteristics:
Leaves

- Hydrangea: Produces large, showy flower heads that can be either mophead (rounded) or lacecap (flat with a ring of larger flowers). Bloom time varies by species, but many bloom later in summer.
Fruit
- Viburnum opulus: Develops bright red berries in the fall that are often used for wildlife food.
- Hydrangea: Typically does not produce prominent fruit; some may develop seed heads after flowering, but these are less noticeable.
Growth Habit
- Viburnum opulus: Generally grows as a larger, upright shrub, reaching heights of 8 to 12 feet (2.5 to 3.5 meters).
- Hydrangea: Varies greatly in size depending on the species, from smaller shrubs to larger varieties, but often has a more rounded or mounded form.
Stem and Bark
- Viburnum opulus: Has a woody, multi-stemmed structure with smooth, grayish-brown bark.
- Hydrangea: Also has woody stems, but the bark may be more textured or peeling in some species, and the stems can be thicker.
Overall Appearance
