Mounding shrub Hydrangea arborescens ‘Annabelle’ has a spread of more than 35 inches. It produces enormous (812) circular heads of pure white blooms in July, which can be trimmed for fresh or dried arrangements. The blooms last until September.
It works well in the mixed border due to its tiny size and summer blossoming. The ‘Annabelle’ hydrangea thrives best in soil that is evenly moist but also well-drained; nevertheless, if moisture is sufficient, she will also grow in full sun. The majority of gardeners clip the branches to the ground in late January because she flowers mostly on growth from the current season (“new wood”). From the root, fresh shoots protrude and bloom that summer. Not a wise choice for gardeners in the Southwest’s arid climate. flowers on fresh wood.
A important genus with about 100 varieties of shrubs and vines, hydrangea is grown for its enormous and spectacular flower heads. The summer and fall, when most woody plants are dormant, are when hydrangeas bloom at their peak, and they are valuable just for that reason.

How soon does Annabelle the hydrangea grow?
After four or five years, the Hydrangea arborescens ‘Annabelle’ will reach a height of 2 meters and a spread of 7 feet. Without a doubt, the massive quantity of enormous white flowers that are produced from late July to early September are the main attraction of this shrub. The blossoms can grow up to 25 cm (10 inches) across under optimal circumstances.
Can you distribute Annabelle hydrangeas?
Annabelle hydrangeas already occupy a lot of space given that they reach heights of between 3 and 5 feet. To fully expand throughout their active growth period, they require a lot of area, but they also typically spread between 4 and 6 feet. These hydrangeas have enormous flowers that are between 8 and 12 inches across when they are in bloom, which is normally in June and July but can occur later.
So seek for some open areas while deciding where to plant your Annabelle hydrangeas. The hydrangea bush should have enough room for you to support it, though, as its large blooms have a tendency to droop. Plant Addicts advises planting at least three Annabelle hydrangeas side by side so that they can support one another as they develop and flourish. To allow for plant growth, you should initially space them 3 to 4 feet apart.
Other alternatives for support include surrounding the plant with a short wire fence or planting Annabelle hydrangeas next to a decorative fence so you may stake the blooms. If you decide to use the short wire fence, set it up around the plant before the spring branch-growth phase so it can support the blossoms from below. Plant your hydrangea bushes 5 to 6 feet apart if you decide to go with one of these methods.
How much room is required by an Annabelle hydrangea?
- Make sure the soil is sufficiently wet and well-draining to meet the needs of the Annabelle Hydrangea.
- Your Annabelle should be placed in a hole deep enough to accommodate the root ball. Additionally, the hole should be roughly three times wider than the root ball.
- Fill the hole with soil halfway.
- Fill the hole with water, then wait until all of the water has evaporated before covering the hole with dirt.
- On top of the filled hole, add more water.

What Can I Plant with Annabelle Hydrangeas?
You can plant other flowering shrubs beside Annabelles as long as you plant them at least three to ten feet apart to give them room to thrive. Just be sure the plants you plant need the same amount of water, sunshine, and fertilizer as Annabelle Hydrangeas.
Small trees like dogwoods are suggested as companion plants because they provide afternoon shade for Annabelle hydrangeas. You can also put these simple-to-grow hydrangeas alongside low annual or perennial plants that prefer partial shade.

What causes Annabelle hydrangeas to wilt?
Massive downpours can be disastrous if you have a garden full of hydrangeas that are in bloom. The flower heads of Annabelle hydrangeas grow so big that when moisture collects on them, it frequently causes the petals to fall to the ground.
This is much more likely if you’ve pruned them because the flowers are on fresh growth, which results in a floppier stem than hydrangeas that bloom on wood from the previous year. When flower heads are heavy and the stems are floppy, they are liable to fall to the ground the moment they get wet.
Are Annabelle hydrangeas sun-loving plants?
I made the decision to plant a flowerbed next to my screened porch several years ago. I wanted a low-maintenance planting that would offer a lovely view from the screened porch and the enclosed garden, which are the two places where we entertain the most. For this east-facing side of the home, a hedge of Hydrangea arborescens ‘Annabelle’ with underplantings of two kinds of green and white hostas was the ideal choice.
I take pleasure in a lovely border that lasts through the last weeks of autumn as soon as the bright green hydrangeas and variegated hostas leaf out in May. Early June sees the appearance of the hydrangea’s lime green buds, which open to reveal enormous white snowball flowers that can measure up to 12 across. The flowers bloom throughout the entire summer, before going back to a delicate green in the early fall and drying to a tawny brown in the winter. The billowy hydrangea blooms are a fantastic accompaniment to my 100-year-old house, and the whole effect is luxuriant yet peaceful.
Why choose the traditional Annabelle hydrangea when there are so many different types available in nurseries? My choice was simple because I had planted Annabelle in another area of the garden for numerous years. Annabelle truly lives up to its reputation for being minimal maintenance, having a lengthy bloom, and not having any major insect or disease issues. In ordinary, well-drained soil in partial shade, Annabelle is simply grown. It can also thrive in fairly deep shade and full sun, though it won’t produce as many flowers in such conditions if they are not exposed to drought. I watered my new hydrangeas frequently the first summer after planting to help them get established. Since then, they haven’t received any further water, and they look fantastic all summer.
Our native Hydrangea arborescens has a really gorgeous cultivar called Annabelle that has flowers that are significantly larger than the natural. A naturally occurring cultivar named Annabelle was found in the wild in Anna, Illinois. It is a 3-5′ tall deciduous shrub with broad, serrated leaves and a rounded shape. It is advised for zones 3-9. It is exceptionally cold-tolerant. Best of all, Annabelle blooms on fresh wood, unlike many other hydrangeas. This is a tremendous benefit for gardeners in the north. Why hydrangeas do not consistently bloom is a question I am frequently asked. Many hydrangeas develop their flower buds on the growth from the previous year, and these buds freeze over the winter, preventing the development of flowers the following year.
Many hydrangea species are prone to bacterial wilt, leaf spot, mildew, and bud blight, but Annabelle has exceptional resilience to these ailments. Despite the relatively sturdy branches of Annabelle, the weight of the blossoms, particularly after a rainstorm, can cause the flowers to droop. Staking, low fencing, grouping multiple plants together, and late-fall or early-spring trimming can all be used to fix this. For winter interest, I like to leave the dried flower heads on the plants. In the spring, I trim the stems down to about 18 inches. At this time, I also get rid of any stems that are dead or have roots that can be used in other parts of the garden. This results in plants with sturdy stems and maintains the size of my shrubs at a manageable level.
The Annabelle hydrangea can be utilized in the garden in a variety of ways, including as a hedge, a specimen, to curb erosion, and in rain gardens. It’s also my go-to place to get dried and cut flowers. I’ve been propagating my shrubs to enhance my supply because it is so beautiful and useful. The simplest technique is to cut out rooted side stems in early spring, especially before they leaf out, using pruners or a sharp spade. These are often grown for a year in a nursery bed, where they have access to the best soil, extra care, and water. Softwood cuttings that are 6 to 8 inches long and soaked in rooting powder in May or June can also root well. Try Annabelle hydrangea and see why it’s arguably the most well-liked flowering shrub in American gardens; it’s commonly accessible in garden centers and in friends’ gardens.
Next to Annabelle hydrangeas, what can I plant?
Shrubs including boxwood, hollies, yews, mahonia, gardenia, and loropetalum look lovely planted in front of hydrangeas. Early color will come from azalea blossoms. Since the azalea flowers will have faded before your hydrangea blooms, you can choose your preferred blossom color.
During the winter, boxwoods and evergreen azalea species will provide some color. Depending on whether you want a formal or natural-looking landscape, boxwoods can be shaped or left in their natural state. These may also offer some wintertime protection from high winds.
How much should Annabelle hydrangeas be pruned back in the fall?
- Annabelle hydrangeas, also known as smooth hydrangeas, bloom on fresh wood, or more specifically, the growth of the current season. The optimum time to prune your bushes is in the late fall or very early spring to ensure that you are not removing any buds.
- Your Annabelles can be deadheaded at any time to remove the wasted flowers. A harsh pruning can occasionally be beneficial for annabelles, but don’t do it every year.
- Go ahead and perform a harsh pruning in the late fall if your bushes are frail and lanky or if your blossoms are small. Reduce the stems to around 18 inches so that the new growth has a strong support system. In the spring, your bushes will develop in thickness and have larger blossoms.
Note from the author: Some professional gardeners advise pruning Annabelles in the late winter or early spring. Others contend that late fall pruning is acceptable. This is how it was described to me when I initially found it confusing: once the growing season begins, do not trim or chop back your Annabelles. So when should an Annabelle hydrangea be pruned? Pruning is acceptable in the very early spring, late winter, or late fall.
Where should hydrangeas not be planted?
growing circumstances The best place to grow hydrangeas is where they will receive morning light and afternoon shade because they require well-draining soil. Both full sun and deep, consistent shadow are unsuitable for hydrangeas. Choose a location where your hydrangeas will receive at least three to four hours of direct sunlight each day.
What occurs if hydrangeas are planted too closely together?
The most often query we receive when building a hedge is, “How far apart should I space my hydrangeas? The answer to this question relies on a number of variables, including the type of hydrangea you’re using, your location, and the style you want to achieve. As a general rule of thumb, focus on the plant’s width first. For instance, Incrediball smooth hydrangeas (seen above) mature to a height and width of 5 feet. As a result, plants can be planted with their centers 5 feet apart such that they will almost touch as they mature.
You might want to think about planting them a little closer if you don’t want to have to wait too long for your hedge to fill up. Plants can grow to their maximum size over a number of years, and in colder climates, this process might take considerably longer. When they are planted closer together, individual plants will eventually touch and overlap. The end product is a beautiful wall of blooms and greenery that is difficult to resist!
Although it may be tempting, be careful not to plant them too closely together. As a result of the restricted airflow caused by their near proximity, disease is more common. Maintain a sufficient distance between plants to allow for airflow and healthy plants (and happy gardeners). On every one of our plant pages, under the “additional information” heading in the “how to grow” tab, are spacing suggestions. You can put Incrediball hydrangeas 3 feet apart if you choose. However, it is recommended that they be planted 3-5 feet apart.
Depending on the plant spacing, you’ll need a certain number of plants for your hedge. To estimate how many plants you need for your area, try using our plant calculator!
How do you stop the spread of Annabelle hydrangea?
Is there anything that can be done to prevent the hydrangea roots from spreading? On the side of our driveway, they “popped” up in a certain spot approximately 5 or 6 years ago. They have expanded excessively, like a wildfire. I tried to pluck them, but it was unsuccessful.
Persistence and a little hard work should be enough. What you want to preserve intact, edge. Cut the rhizomes (underground stems that resemble roots) with a sharp spade to separate the hydrangeas you want to maintain from those you want to get rid of. Whenever the undesirable stems appear, continuously prune them to the ground. These stems ought to become weaker and eventually perish. Alternately, carefully apply a complete vegetation killer to the unwanted sprouts. All plants, even the ones you want to maintain, risk injury or death if the rhizome is not severed before spraying. When using conventional or new environmentally friendly products, read and carefully abide by all label instructions. All of these items are plant killers and can harm or kill both your desired plants and weeds.
Are Hardy Annabelle Hydrangeas?
A huge, bushy shrub native to North America called Hydrangea aborescens produces sterile flowers that are larger and more showy than the fertile ones and have colored bracts in place of petals. Only sterile florets are present in Hydrangea aborescens ‘Annabelle’ flower heads, which are significantly larger and resemble stunning white balls that can reach a diameter of 30cm. It has received The Royal Horticultural Society’s esteemed Award of Garden Merit (AGM).
Growing conditions for Hydrangea aborescens ‘Annabelle’ are full sun to moderate shade, moist but well-drained soil. Although plants are supposedly very tough, late frosts might harm the buds, therefore in cold areas, grow them in a protected corner or up against a warm wall. The naturally open plants are kept thick and compact by routine pruning.
How are Annabelle hydrangeas cared for in the winter?
If the hydrangea has to be renewed, prune it when the barren branches are showing in the fall dormancy. Since Annabelle blooms on fresh wood, dormant pruning has no effect on the number of blooms. At ground level, remove a few of the oldest stems. Once you have removed one-third of the plant, keep taking out the oldest wood.
Tip
Place your Annabelle hydrangea where it will be shielded from the summer’s sweltering afternoon sun. A well-established shrub in an open area that you inherited needs more water in the summer.
Warning
Since the Annabelle hydrangea blooms profusely in the spring, some gardeners cut it down to the ground every fall. But if you can, avoid this severe pruning. It weakens the plant, and eventually the hydrangea stalks might need to be anchored.
