Annabelle Hydrangea Shrubs for Sale Online
Native to the United States, the Annabelle Hydrangea (Hydrangea arborescens) is a naturally occurring cultivar that yields magnificent white flower clusters that can grow to 10 inches in diameter. Reaching up to 5 feet tall and wide, these show-stoppers are an excellent centerpiece for a border garden.
If you reside in a climate unsuitable for macrophylla hydrangeas, this native hydrangea is an excellent alternative. It consistently regrows each season despite challenging conditions. While it thrives in morning sunlight, it needs afternoon shade in warmer areas but prefers full sun in cooler regions. Blooming from July to September, the Annabelle shrub's pure white blossoms beautifully contrast with its deep green foliage.
The blooms on the Annabelle Hydrangea are so large that the branches can sag after rain from the weight of its flowers. As a result, these flowering shrubs are often used as hedges where they can support each other as they grow and provide privacy in a beautiful and unexpected way.

How to Care for Annabelle Hydrangea
Be sure to read our planting instructions to ensure a healthy and happy plant for years to come!
How do I plant my Annabelle Hydrangea?
Dig a hole twice as wide as the root system, but not deeper. Loosen the roots of the plant gently with your fingers to encourage outward root growth. Hydrangeas prefer well-draining soil. You can mix compost in with your existing soil, aiming for a 50/50 mix. Especially in clay soil, this addition of compost, or organic matter, helps to create air pockets that will improve drainage. Add in some of your amended soil into the hole and sprinkle in a starter fertilizer. Place your plant in the hole, making sure that the base of the main stem (or crown) of the plant is even with the ground level. Back-fill the hole with well-draining soil, and press down firmly all around the base of the plant. Give your newly planted hydrangea a deep watering. Let the water drain completely, and then water again.
How do I water my smooth Hydrangea shrub?
Depending on your area's rainfall, you may need to water hydrangeas every day or as little as once a week. Pay very close attention to your hydrangeas in the heat of summer. A way to determine when to water is to test the soil with your finger to a depth of about two inches. If the soil is dry, it needs to be watered. If hydrangea leaves are drooping, it is time to water. Water the ground underneath the entire width of the stems. Avoid watering on top of the leaves, which can weaken the plant and make it vulnerable to fungus. Hydrangeas that are in wet, boggy conditions do not thrive.
How do I fertilize Annabelle Hydrangeas?
The Annabelle Hydrangea is known for its voluptuous white blooms. To encourage blooming, apply fertilizer in spring or early summer. Select a fertilizer that is high in phosphorus, such as Jack’s Classic Blossom Booster. Follow instructions on the packaging.
How do I mulch Annabelle hydrangeas?
In order to protect your plant's roots from harsh winters, retain moisture, and ward off unwanted and intrusive weeds, it is important to surround your Annabelle Hydrangea will mulch. We recommend organic mulch such as a ground hardwood or cypress mulch. Using an organic mulch will provide the shrub with additional nutrients as the mulch decomposes, resulting in even more beautiful blooms. Make sure you leave about 3 inches of space between the base of the plant and the mulch line so the tree can breathe. This will also prevent the roots and stem from becoming waterlogged and risking root rot.
