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 be 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 live in a harsher climate that cannot support a macrophylla, this deciduous hydrangea is the perfect alternative. It never fails to regrow every season, despite threatening conditions. This hydrangea loves to bask in the morning sun but requires afternoon shade in warmer climates. Whereas, in cooler locations, full sun is preferred. Blooming in July and lasting through Septemeber, the pure white blossoms of the Annabelle shrub are a pleasant contrast to their deep green foliage.The blooms on the Annabelle Hydrangea are so large, in fact, that the branches can sag after rain from the weight of its flowers. As a result, these shrubs are often used as hedges where they can support each other as they grow and provide privacy in a beautiful and unexpected way.
