The Annabelle Hydrangea is a hardy shrub that displays stunning white blossoms that can reach 12” in diameter. The Annabelle is one of the oldest flowering shrubs that can be found in an American garden! Don’t miss out on a classic shrub that will continue to bloom year after year.

Enjoy continuous flower cuttings right from your own yard! As your hydrangea blooms, take cuttings and make your own flower arrangements indoors!

The Annabelle typically grows 3-5 feet tall. Clusters of dazzling white flowers form in huge rounded heads called corymbs that can reach a diameter of 12.” Wow! Those are some pretty large flower heads. The flowers are produced in the summer months, and will re-bloom during fall. That’s double the bloom time. It prefers partial shade, but will tolerate heat. Once the Annabelle Hydrangea is established, it is easy to grow.

This hydrangea prefers partial shade, so ensure that this is taken into consideration when deciding of the placement of your new hydrangea. Make sure that you plant in well-drained soil and it is planted no deeper than the pot it is planted in. Water your hydrangea after planting and maintain a regular watering cycle. Prune your Annabelle Hydrangea after the summer flowers have faded away in the summer. Remove all dead stems and flower heads. This hydrangea blooms on new wood so you can prune heavily in the dormant season.

How To Care

When planting your Annabelle Hydrangea be sure you have the right location and conditions for your new plants to thrive. Spring and Fall are ideal times to plant Hydrangeas. Avoid planting hydrangeas in summer when temperatures are mid80s or higher.

The Annabelle Hydrangea requires full sun to part shade and prefers moist, well-drained, fertile soil. In hot climates, hydrangeas will do best with some shade. This variety's color is not affected by soil pH. Keep the soil moist, but not saturated, especially in summer and in the first year after planting. Throughout its life Hydrangeas will do best with a deep watering once weekly during hot temperatures. Mulching at about 3 inches deep is highly recommended for hydrangeas. Mulching will cut back on watering needs and protect your plant in extreme temperatures. Choose a slow release fertilizer for flowering plants. Fertilize once in spring after the last chance of frost and again in early summer for best results. You don’t need to prune hydrangeas, but pruning lightly after they are done blooming can help encourage a bushier growth and renew an older plant. This hydrangea grows on new wood so you can prune more heavily in the dormant season. Check out our blog post on When To Prune Flowering Shrubs.

The best way to prevent disease and pests is by providing the appropriate care for your plants. Proper location choice, watering, and fertilization are the keys to your success. You can treat mites, scale, whiteflies, and aphids naturally with neem oil or insecticidal soap. For severe infections you can use pesticides like carbaryl, also known as Sevin. Fungal infection can be prevented by making sure the planting site has good drainage and by avoiding overhead watering. Fungal infections can be treated with a fungicide. Generally, treating fungus after infection isn't effective so if you have problems with other plants or in a prior year, treat preventatively in early spring.

Best On-line Nursery Ever!

Prompt shipping. I placed an order and a few min. later realized I ordered the wrong plants. Before I could write them back to say cancel that order they had written me back saying my order had been confirmed and was being processed. I went ahead and sent a new order and asked again that they cancel the 1st order. They communicated, straightened everything out and I had my plants within 24 hours! Plants were big, beautiful and healthy. This is my 2nd time ordering and I will be here for all my future needs.
