This stunning plant is known for its large, showy blooms and easy-to-grow nature. In this guide, we will explore everything you need to know about growing and caring for Annabelle hydrangeas.

What is an Annabelle Hydrangea?

Annabelle hydrangeas, also known as smooth hydrangeas, are a type of hydrangea that originated in North America. These plants are renowned for their large, round blooms that range from pure white to pale green. Unlike other hydrangea varieties, Annabelle hydrangeas bloom on new wood, meaning they can be pruned in the fall or early spring without sacrificing blooms.

Choosing the Right Location

Annabelle hydrangeas prefer partial shade to full sun, making them an excellent choice for a variety of garden settings. When choosing a location for your plant, consider the amount of sunlight it will receive throughout the day. Too much direct sunlight can cause the plant's leaves to wilt and brown, while too little can prevent it from blooming properly.

Caring for Your Annabelle Hydrangea

Once you've chosen the perfect location for your Annabelle hydrangea, it's time to caring for it. Here are some tips to help you keep your plant healthy and happy:


Annabelle hydrangeas require regular watering, especially during hot, dry weather. Be sure to water deeply, soaking the soil around the plant's roots. Avoid getting water on the plant's leaves or blooms, as this can cause damage.


To encourage healthy growth and blooming, it's important to fertilize your Annabelle hydrangea regularly. Use a balanced fertilizer with equal amounts of nitrogen, phosphorus, and potassium. Apply the fertilizer in early spring and again in mid-summer.

Pruning Your Annabelle Hydrangea

As we mentioned earlier, Annabelle hydrangeas bloom on new wood, meaning they can be pruned without sacrificing blooms. Prune your plant in the fall or early spring, removing any dead or damaged branches and shaping the plant as desired.


If you want to propagate your Annabelle hydrangea, it's best to do so in the spring or early summer. Take cuttings from the plant's new growth and root them in a well-draining potting mix. Keep the cuttings moist and out of direct sunlight until they develop roots.

Pests and Diseases

While Annabelle hydrangeas are generally hardy and resistant to pests and diseases, there are a few things to watch out for. Common pests include aphids, spider mites, and scale insects, which can be controlled with insecticidal soap or neem oil. Diseases such as powdery mildew and leaf spot can also affect these plants, but can be prevented by keeping the plant's leaves dry and providing good air circulation.

Common Uses for Annabelle Hydrangeas

Annabelle hydrangeas are a versatile plant that can be used in a variety of ways. Here are just a few ideas:
