Understanding the Smooth Hydrangeas: Annabelle and Incrediball
Both ‘Annabelle’ and ‘Incrediball’ are cultivars of Hydrangea arborescens, commonly known as smooth hydrangeas. This means they share a lot of fundamental traits, like blooming on new wood each year, making them incredibly reliable for flowers even after a harsh winter.
They are also native to North America, which makes them excellent choices for many gardens, thriving in a wide range of climates. Their hardiness and relatively low maintenance are why they’ve become such beloved landscape staples.
These beautiful shrubs are famous for their large, spherical flower heads, which start green, mature to brilliant white, and often fade to a charming parchment color in fall. They truly offer a long season of interest!
The Classic: Hydrangea arborescens ‘Annabelle’
‘Annabelle’ has been a garden favorite for decades, celebrated for its spectacular, dinner-plate-sized white flower clusters. It’s a classic for a reason, bringing a touch of timeless elegance to any setting.
Gardeners love ‘Annabelle’ for its generous blooming habit and robust nature. It’s a true workhorse in the garden, providing a consistent display year after year.
However, ‘Annabelle’ can sometimes present a challenge: its stems can be a bit on the floppy side, especially after a heavy rain or when the enormous blooms are fully open. This is a common point of discussion among gardeners.
The Breakthrough: Hydrangea arborescens ‘Incrediball’
Enter ‘Incrediball’, a newer cultivar specifically bred to address some of ‘Annabelle’s’ limitations, particularly the flopping stems. It was introduced as part of the Proven Winners ColorChoice program.
‘Incrediball’ promises stronger stems capable of holding up its equally massive, if not larger, flower heads. This makes it a popular choice for those seeking the ‘Annabelle’ look with improved structural integrity.
It also boasts an impressive flower size, often exceeding ‘Annabelle’s’ in diameter. The sheer scale of its blooms can be breathtaking, creating a truly dramatic impact in the garden.
annabelle hydrangea vs incrediball: A Head-to-Head Comparison
Let’s get down to the nitty-gritty and compare these two smooth hydrangea superstars side by side. Understanding their differences will help you decide which one is the perfect fit for your gardening style and landscape design.
Flower Size and Appearance
- Annabelle: Known for its classic, pure white, rounded flower heads that can reach 8-10 inches across. The blooms are typically more dome-shaped.
- Incrediball: Often boasts even larger blooms, sometimes up to 12 inches or more in diameter. The flowers tend to be more perfectly spherical and incredibly dense, living up to their “Incrediball” name!
Both start green and mature to white, but ‘Incrediball’s’ blooms can sometimes appear a brighter, more pristine white initially.
Stem Strength and Structure
This is arguably the most significant differentiator between the two cultivars.
- Annabelle: The older stems can be a bit weak, leading to flowers flopping over, especially after rain or when fully open. Many gardeners learn to support them with stakes or strategically plant them amongst other shrubs.
- Incrediball: Bred specifically for stronger, sturdier stems that are much better at holding up those massive flower heads. This is a huge advantage for a tidy, upright appearance throughout the season.
If you’re tired of seeing your beautiful blooms bowed to the ground, ‘Incrediball’ offers a compelling solution.
Growth Habit and Mature Size
Both are deciduous shrubs, but their overall mature size and shape can vary slightly.
- Annabelle: Typically grows to about 3-5 feet tall and wide, forming a rounded, somewhat sprawling mound. It can spread a bit over time.
- Incrediball: Generally a bit larger, reaching 4-5 feet tall and wide, often with a slightly more upright and compact growth habit due to its stronger stems.
Consider the space you have available and how much spread you’re comfortable with when making your choice.
Hardiness and Climate Zones
As Hydrangea arborescens cultivars, both are incredibly cold-hardy.
- Annabelle: Hardy in USDA Zones 3-9.
- Incrediball: Also hardy in USDA Zones 3-9.
This means gardeners in most parts of North America can successfully grow either variety, enjoying reliable blooms even after very cold winters.
Bloom Time and Longevity
Both varieties bloom on new wood, meaning they produce flowers on the growth that emerges in the current season.
- Annabelle: Typically starts blooming in early to mid-summer and continues well into fall.
- Incrediball: Also blooms from early summer through fall, often with a slightly longer bloom period due to its robust nature.
You’ll get a long season of beautiful white flowers from either choice, a definite win for any garden!
Cultivation and Care: Keeping Your White Hydrangeas Thriving
Whether you choose ‘Annabelle’ or ‘Incrediball’, the general care requirements are quite similar. These smooth hydrangeas are known for being relatively unfussy, making them perfect for gardeners of all skill levels.
Don’t worry—these flowers are perfect for beginners! With a few key practices, you’ll have them flourishing.
Sunlight Requirements
Smooth hydrangeas prefer a location with morning sun and afternoon shade, especially in hotter climates. This helps protect their leaves and blooms from scorching.
In cooler northern zones, they can tolerate more sun, even full sun, as long as they receive adequate moisture. Aim for at least 4-6 hours of sun for best blooming.
Soil and Watering
These hydrangeas thrive in rich, well-draining soil. Amend heavy clay soils with compost to improve drainage and aeration. They also appreciate slightly acidic to neutral soil pH (around 6.0-7.0).
Consistent moisture is key, especially during their first year and during dry spells. Water deeply and regularly, aiming for about an inch of water per week, either from rainfall or irrigation.
A good layer of organic mulch (2-3 inches) around the base of the plant will help retain soil moisture, regulate soil temperature, and suppress weeds. Just be sure to keep it away from the stems to prevent rot.
Pruning for Success
Since both ‘Annabelle’ and ‘Incrediball’ bloom on new wood, pruning is incredibly simple and forgiving. You can prune them back hard in late winter or early spring before new growth emerges.
- Timing: Late winter or early spring, after the last hard frost but before new shoots get too long.
- Method: Cut back all stems to about 6-12 inches from the ground. This encourages strong new growth and larger blooms.
- Benefits: Hard pruning helps strengthen the stems and keeps the plant at a manageable size. For ‘Annabelle’, it can sometimes help reduce flopping, as the new growth will be thicker.
If you prefer a taller plant, you can prune less severely, only removing dead, damaged, or weak stems. However, most gardeners find that a hard prune produces the best results for these varieties.
Fertilizing Your Hydrangeas
Smooth hydrangeas are not heavy feeders. A balanced slow-release granular fertilizer applied in early spring is usually sufficient. Look for a fertilizer with an NPK ratio like 10-10-10 or similar.
Avoid over-fertilizing, especially with high-nitrogen fertilizers, as this can encourage leafy growth at the expense of flowers. A yearly top-dressing of compost around the base of the plant can also provide ample nutrients.
Common Challenges and How to Solve Them
Even with their generally easy-going nature, ‘Annabelle’ and ‘Incrediball’ can encounter a few common issues. Knowing what to look for and how to respond will keep your plants healthy and beautiful.
Floppy Stems (Mainly ‘Annabelle’)
This is the classic ‘Annabelle’ dilemma. The sheer weight of its enormous blooms, especially when wet, can cause stems to bend or break.
- Solution 1: Strategic Pruning: Prune back harder in spring (to 6-12 inches) to encourage thicker, sturdier new growth.
- Solution 2: Support: Use a peony cage or individual stakes around the plant as it grows. Install these early in the season before the plant gets too large.
- Solution 3: Companion Planting: Plant ‘Annabelle’ amidst other sturdy shrubs or perennials that can offer some support as it grows.
- Solution 4: Consider ‘Incrediball’: If flopping is a major concern, switching to ‘Incrediball’ is your best bet for a more upright display.
Lack of Blooms
If your hydrangea isn’t blooming, consider these factors:
- Not enough sun: While they appreciate shade, too much shade can inhibit flowering. Ensure they get at least 4 hours of sun.
- Over-fertilization: Too much nitrogen encourages leafy growth, not flowers. Use a balanced fertilizer sparingly.
- Improper pruning: While these bloom on new wood, pruning too late in the season (after new growth has formed flower buds) can reduce blooms. Stick to late winter/early spring.
- Extreme weather: Very late frosts can sometimes damage emerging buds.
Pests and Diseases
Smooth hydrangeas are generally quite resistant to serious pests and diseases, but occasional issues can arise.
- Aphids: Small green insects often found on new growth. A strong spray of water can dislodge them, or use insecticidal soap for larger infestations.
- Spider Mites: More common in hot, dry conditions. Look for fine webbing and speckled leaves. Increase humidity around the plant and use insecticidal soap.
- Powdery Mildew: A white, powdery coating on leaves, usually in humid conditions with poor air circulation. Ensure good spacing between plants and improve air flow. Fungicidal sprays can be used if severe.
- Leaf Spot: Various fungal spots can appear. Remove affected leaves and ensure good garden hygiene.
Always inspect your plants regularly to catch any issues early. Healthy, well-cared-for plants are naturally more resistant.
Designing Your Garden with White Hydrangeas
Both ‘Annabelle’ and ‘Incrediball’ are incredibly versatile in the landscape. Their pure white blooms provide a crisp, clean look that complements almost any garden style.
Mass Plantings and Borders
For a truly dramatic effect, plant several ‘Annabelle’ or ‘Incrediball’ hydrangeas in a mass planting. Their large white blooms create a stunning visual impact, especially when viewed from a distance.
They also make excellent border plants, defining garden beds or pathways with their elegant presence. Their consistent summer bloom is a major asset.
Specimen Plants and Foundation Plantings
A single, well-grown ‘Incrediball’ can serve as a magnificent specimen plant, drawing the eye with its robust form and enormous flowers. ‘Annabelle’ can also work, especially if given some support or allowed to naturalize.
Both are fantastic for foundation plantings around your home, adding beauty and softening architectural lines. Just ensure they have enough space to reach their mature size.
Companion Plants
White hydrangeas pair beautifully with a variety of other plants. Consider these companions:
- Hostas: Their large, textured leaves provide a wonderful contrast in form and color.
- Ferns: Delicate fronds offer a soft, naturalistic look, especially in shadier spots.
- Astilbes: Their feathery plumes offer vertical interest and bloom in similar conditions.
- Evergreens: Provide year-round structure and a dark green backdrop that makes the white blooms pop.
- Perennials with purple or blue flowers: Think salvia, catmint, or delphinium for a cool, sophisticated color palette.
When selecting companion plants, consider their light and moisture needs to ensure they thrive alongside your hydrangeas.
Frequently Asked Questions About Smooth Hydrangeas
Here are some common questions gardeners ask about these popular white hydrangeas.
Do ‘Annabelle’ and ‘Incrediball’ change color?
Unlike some Hydrangea macrophylla varieties, the flower color of ‘Annabelle’ and ‘Incrediball’ (which are Hydrangea arborescens) is not affected by soil pH. Their blooms emerge green, turn pure white, and then often fade to a lovely parchment or greenish hue in the fall as they age.
Are ‘Annabelle’ and ‘Incrediball’ deer resistant?
While no plant is entirely deer-proof, smooth hydrangeas like ‘Annabelle’ and ‘Incrediball’ are generally considered more deer-resistant than other hydrangea species, such as Hydrangea macrophylla (bigleaf hydrangeas). Deer may browse them if other food sources are scarce, but they are not usually their first choice.
Can I grow these hydrangeas in containers?
Yes, both ‘Annabelle’ and ‘Incrediball’ can be grown successfully in large containers, especially when young. Choose a pot that is at least 18-24 inches in diameter to allow for root growth. Container-grown hydrangeas will require more frequent watering and feeding than those in the ground, and may need winter protection in colder zones.
When is the best time to plant ‘Annabelle’ or ‘Incrediball’?
The best time to plant smooth hydrangeas is in spring or early fall. This allows the plants to establish their root systems before the stress of summer heat or winter cold. If planting in summer, be diligent with watering.
What is the difference between ‘Incrediball’ and ‘Invincibelle Spirit’?
Both ‘Incrediball’ and ‘Invincibelle Spirit’ are Hydrangea arborescens cultivars from Proven Winners. The main difference is flower color: ‘Incrediball’ has large white blooms, while ‘Invincibelle Spirit’ (and its improved version ‘Invincibelle Spirit II’ and ‘Invincibelle Wee White’) features beautiful pink flowers. They both share the strong stem characteristic.
