Incrediball Hydrangea vs Annabelle: 4 Key Differences

Hi everyone! Today, I’m excited to talk about two amazing hydrangea varieties: Incrediball and Annabelle. Let’s compare them!

The main difference between Incrediball Hydrangea and Annabelle Hydrangea lies in their flower heads and stem strength. Incrediball Hydrangea, known for its massive blooms, features large, strong stems that prevent drooping, even with large flowers. These flowers are typically white and can grow up to 12 inches in diameter.

On the other hand, Annabelle Hydrangea is famous for its smaller, but still impressive, white flowers that can reach up to 10 inches across. However, Annabelle’s stems are thinner, which can lead to drooping, especially after heavy rain.

The first key difference between Incrediball and Annabelle hydrangeas is their flower size. Incrediball boasts larger blooms, with flower heads reaching up to 12 inches, compared to Annabelle’s maximum of 10 inches. However, Annabelle tends to have more flower heads than Incrediball.

The blooming period for both varieties typically starts in June or July, depending on the local climate. Their flowering season usually lasts around two months.

Another distinction is in the color change during blooming. Incrediball hydrangeas initially display a light green (lime) hue, which gradually turns to pure white over a few weeks. In contrast, Annabelle’s flowers are pure white right from the beginning.


The stunning large flower heads of hydrangeas, while visually impressive, come with a drawback – their weight. Under calm conditions, this isn’t an issue. However, during rainy and windy weather, or in a storm, these beautiful plants can suffer damage.

This is particularly true for the Annabelle variety. If the blossoms become soaked in heavy rain, even a slight breeze can cause the bush to collapse, leading to its white flower heads dropping to the ground. The branches of Annabelle hydrangeas are slender and prone to breaking or bending.

Incrediball hydrangeas, on the other hand, have stronger and thicker stems, making them more resilient to heavier loads. Yet, they are not invincible. In severe storms, even Incrediball hydrangeas might struggle to hold up.


The final subtle difference between Annabelle and Incrediball Hydrangeas lies in their size and shape.

Incrediball typically grows to a height of 3 to 5 feet and spreads equally wide. Over a few years, it forms into a large, ball-shaped bush.

Annabelle, in contrast, can reach up to 5 feet in height but may spread wider, up to 6 feet or slightly more. This results in a somewhat flattened shrub appearance. It’s a minor distinction, but notable.

For a hydrangea with a more uniform, ball-like shape, Incrediball would be the preferred choice.

Growing Conditions

To achieve optimal blooming in Incrediball Hydrangeas, which require more energy than their counterparts for their larger flower clusters, it’s crucial to provide the plant with all necessary conditions. Otherwise, you might not see the desired results.

Firstly, sunlight is key. Plant Incrediball Hydrangeas in a location where they receive at least 5 hours of direct sunlight daily. In northern areas, they need more sunlight, while in hotter climates, semi-shade is beneficial.

Secondly, consider their water needs. Hydrangeas generally love water due to their large leaves that lose a lot of moisture. Typically, water Incrediball twice a week if there’s no rain. During extreme droughts, increase the watering frequency.

Thirdly, proper nutrition is essential. Apply a slow-release fertilizer early in spring. Opt for a fertilizer with a higher phosphorus content, as phosphorus promotes larger and more beautiful flowers. Avoid high-nitrogen fertilizers, as they encourage leaf growth over flower development.

Finally, mulch around Incrediball Hydrangeas using high-quality compost. This not only provides additional nutrients but also helps retain moisture near the roots. Keep the mulch layer 2 to 3 inches thick and avoid placing it directly on the stems.


In conclusion, when deciding between Incrediball and Annabelle Hydrangeas, it’s important to consider their distinct characteristics. Incrediball Hydrangeas are known for their larger flower heads, sturdier stems, and ball-shaped growth, making them a great choice for gardeners seeking impressive blooms and a more uniform shape.

Annabelle Hydrangeas, with their slightly smaller yet abundant flowers and wider, more flattened growth, offer a charming alternative, especially in spaces where a sprawling shrub is desired. Both varieties have specific sunlight, water, and nutritional needs to thrive and showcase their unique beauty.

Ultimately, the choice between Incrediball and Annabelle Hydrangeas depends on personal preference and garden aesthetics, with both varieties bringing their own special charm and elegance to any garden.
