Origin
The Hydrangea arborescens 'Annabelle', commonly known as the Annabelle Hydrangea, originally hails from the eastern part of North America. It is a cultivated variety discovered in the 1960s in the garden of a woman named Annabelle. The plant quickly gained popularity, first in the United States, and then in Europe and the rest of the world.
Characteristics
The Hydrangea arborescens 'Annabelle' is characterised by its striking, large, white flower heads, which can reach a diameter of 20 to 30 centimetres. The flowering is very abundant and lasts from June until September. The plant does not grow very tall, the average height varies from one to one and a half meter. Under the right conditions, the 'Annabelle' can develop into a beautiful deciduous shrub with a full, round structure.
Care
The Hydrangea arborescens 'Annabelle' thrives best in partial shade and prefers a fertile, well-draining soil. The plant has a medium water requirement and needs additional irrigation during dry periods. It is recommended to prune the plant back to a height of about 30 centimetres each year in March to promote lush flower production. Afternoon shade is recommended to avoid wilting of the flowers and help preserve the beauty of the shrub.
