The Smooth Hydrangea arborescens variation most commonly found is called Annabelle. This is the only Hydrangea arborescens variety that was formerly simple to find at garden centers or even known to the general public.
Beautiful white blooms with heads that are frequently larger than 10″ are produced by Annabelle Smooth Hydrangea. Annabelle flowers every year, even after harsh pruning or bitterly cold winters, unlike the more well-known blue and pink hydrangeas (macrophyllas). The enormous, white “drumstick” blossoms consistently sprout in abundance. ‘Annabelle’ is sometimes grown as a hedge since it may be severely pruned for a clean appearance in the winter.
Both in both hot and cold climates, “Annabelle” puts on a stunning performance. There have been indications that it can survive in American Zones 2 and 3. (officially rated to to Zone 3). In reality, eastern regions of the United States are home to varieties of Hydrangea arborescens. ‘Annabelle’ would be a fantastic substitute if your climate makes it difficult to cultivate macrophyllas.
Do Annabelle hydrangeas come in a variety of hues?
Depending on the pH of the soil, bloom colors can range from blue to pink and all the colours in between. The pH scale identifies the soil’s acidity or alkalinity.
Generally speaking, the pH of your soil can be determined by the bloom color of lacecap, mophead, or Macrophylla hydrangeas. Blue or lavender-blue blooms are produced in soil with a pH under 6.0. Pink and red blossoms grow on alkaline soil, which has a pH level above 7.0. Purple to blue blooms can be seen anywhere between 6.0 and 7.0. White hydrangeas usually maintain their color.
Some hydrangea types, such as practically every Macrophylla variety (like the Proven Winner’s Cityline Hydrangea) and Serrata variety (like the Proven Winner’s Tiny Tuff Stuff Hydrangea), allow for the adjustment of bloom color. The following hydrangeas cannot change color:
- Arborescens-Annabelle
- Paniculata-Limelight
- Anomola-Climbing
- Oakleaf Quercifolia
The majority of these are cone-shaped Hydrangeas that bloom in various colors of white before gradually fading to pink in the fall. It is impossible to modify the color of the well-known Annabelle Hydrangeas, which have huge white ball-shaped blooms as well as more recent pink varieties.
Conducting a soil test to assess the pH of your soil is the first step in the color change process. An employee at your neighborhood English Gardens will do a customized in-store soil test consultation using a sample of your soil.
Use Espoma Garden Lime, available at all English Gardens locations, to increase the pH in your garden and produce pink blossoms. Employ Espoma Soil Acidifier to reduce the pH of the soil and induce blue blooms.
It’s a waiting game once the appropriate products have been applied. It can take multiple reapplications and months before you see a change. It takes repeated soil amendments to modify a hydrangea’s hue. You’ll need to keep adding minerals to your soil to maintain the changing conditions.
Why pick between purple, pink, or blue? All three are featured in a stunning variety of colors in LA Dreamin’, which cannot be colored. It is a hardy hydrangea that continues to bloom throughout Michigan’s harsh winters. It also makes a wonderful cut flower that keeps well in any vase.
In the months of July and August, free workshops on hydrangeas are offered. To view a complete schedule, go to our events page.
Can blue Annabelle hydrangeas bloom?
But it goes a little bit deeper than that. To begin with, not all hydrangeas bloom with blue flowers. The only hydrangeas that can produce white or cream flowers are those of the PeeGee family, the Annabelle hydrangeas, and oakleaf hydrangeas.
Why do hydrangeas named Annabelle turn green?
As they ripen, hydrangea blooms all change color. Hydrangeas that are pink and blue frequently turn green (especially in the South where climates are hot and humid). The blossoms may take on pink and burgundy tones when they turn green.
White-flowered Annabelle hydrangeas ALWAYS turn green after about two weeks of blooming (sometimes they stay white a little longer).
One can select hydrangea blooms for dry arrangements when they have matured and changed hues (see: Drying Naturally). The dark, ugly petals can be removed using scissors.
[NOTE] On occasion, hydrangeas that typically bloom in pink or blue become green. Nobody appears to know what causes it, but it frequently lasts just one or two years before the blooms change back to their regular hue. Utilizing a fertilizer with trace elements could hasten the process of returning to a normal hue.
Some hydrangeas mature to stunning blue and purple hues in temperate climes (and occasionally in hot ones). As far as I’m aware, the only thing we can do to encourage these gorgeous hues is to make sure the plants are well-hydrated.
How Big Do Annabelle Hydrangeas Get?

How Fast Do Annabelle Hydrangeas Grow?
Annabelle hydrangeas planted in the spring will bloom in the middle to end of the summer. Annabelle hydrangeas may also bloom in the early fall, depending on the growing environment. This plant rests in dormancy until the next spring after its final flowering. With the right care, it can withstand harsh winters pretty well and will bloom for many years.
Can Annabelle Hydrangeas Take Full Sun?
Annabelle hydrangeas can be planted in full sun or partial shade, but as with most plants, too much direct sunshine can stress them out and make them wilt. In the warmer, southern parts of the US, when growing Annabelle Hydrangeas, keep in mind how much stronger the sun is in the summer and think about putting them in partial shade or covering plants for a few hours in the afternoon. The best locations for Annabelle Hydrangea planting are those that get full morning sun and half afternoon sun.
How Do You Prune an Annabelle Hydrangea?
In order to encourage a second cycle of magnificent blooms, Annabelle hydrangeas respond well to pruning by removing faded blossoms and a few inches of new growth. Wait until late September or early October before pruning. Never prune flowers until they have faded noticeably. An Annabelle Hydrangea plant’s thorough renewal pruning entails eliminating the oldest stalks all the way to the ground. Just before spring, cut any stems that are protruding above the soil’s surface to promote growth as the sun’s energy increases.
Overly dry soil
To keep Annabelles moist, plant them in rich, humus soil or mulch the soil with two to three inches of wood chips. Every Hydrangea has a short root system that is prone to drying out.
Diseases such as rust, powdery mildew, and leaf spots
Plant your annabelles in regions with good air circulation to protect them from these illnesses. Instead of utilizing overhead sprinklers to water plants, drip irrigation performs better at keeping plants disease-free. Plant diseases like mildew and leaf spot can be treated with fungicides on hydrangeas.
Pests such as mites or aphids
The Annabelle Hydrangea’s stems and leaves contain plant liquids that mites and aphids feed on, robbing the plant of the nourishment it needs to blossom. Sticky honeydew covering the leaves is a surefire symptom of an aphid or mite infestation. Plants can be treated with horticultural oils or insecticidal soap to get rid of mites or aphids.
When Do Annabelle Hydrangeas Bloom?

However, Annabelle Hydrangeas require monthly application of deer repellent spray to maximize its efficacy.
How can Annabelle hydrangeas be kept white?
A lot of people are drawn to hydrangeas because of their vivid and exquisite colors. Several of them even alter their color! It’s no surprise that they’re so well-liked with their enormous blossoms and large, glossy green leaves. Don’t let that deceive you, though; adding a stylish white Hydrangea plant to your yard is just as attractive.
Focus on maintaining the health of your white hydrangeas by giving them the right amount of water, light, and fertilizer. If your white Hydrangea is becoming blue or pink, you definitely don’t have a true white variety because white Hydrangeas don’t change color with soil pH like blue and pink blooms do.
How can I dye my hydrangeas a deep blue color?
The chemistry of the soil, not what is sprayed to the blooms, is what determines how colored hydrangea blossoms turn out to be. The color of the blossoms will increase with soil alkalinity. Some varieties stay pink at a neutral pH, while others begin to display lovely lavender hues with hints of blue. Acidic soils, usually with a pH of 5.5 or less, are ideal for blue hydrangea blooming.
Aluminum sulfate, which is readily accessible at practically any garden center, is the simplest way to acidify your soil and turn those babies blue. Mix 1/4 oz aluminum sulfate with a gallon of water and soak the soil surrounding your hydrangeas in the spring, as soon as the plant begins to grow. Reapply in 4 weeks and again in 8 weeks because you’ll need to keep that acidity throughout the growing season.
Another, more organic way to increase soil acidity is to add organic materials like coffee grounds, egg shells, or citrus fruit peels. Simply break them up and till the soil with them. It might take a full year of doing this consistently for the changes to occur gradually, resulting in the proper acidity.
Do hydrangeas turn blue from coffee grounds?
- Maintain low amounts of phosphorus, moderate levels of nitrogen, and high levels of potassium in the soil in order to make sepals bluer.
- Maintain high levels of nitrogen and moderate amounts of phosphorus while adding garden lime to the soil to give sepals a pinker hue.
- This should be completed in late autumn or early spring, well before flowering.
Can coffee grounds be used to change the color of hydrangeas?
Some gardeners claim that adding coffee grounds to the soil helped them successfully dye their hydrangeas blue. The soil becomes more acidic thanks to the coffee grounds, which makes it easier for the hydrangea to absorb metal. Fruit peels, grass clippings, peat moss, and pine needles are also believed to have a comparable impact.
Can eggshells be used to change the color of hydrangeas?
Crushed eggshells might be a good approach to grow pink hydrangeas. Eggshells will gradually degrade and lessen the acidity of your soil, which will make it more difficult for hydrangeas to absorb metal.
How do I make blue hydrangeas with vinegar?
To adjust the soil’s acidity and colour their hydrangeas blue, many gardeners add vinegar to their watering can. However, if you use Hydrangea Blue, a liquid fertilizer that yields blue flowers, you’ll probably get greater results.
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.
Hydroangeas Annabelle tolerant of full sun?
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.
