Hydrangea arborescens 'Annabelle' (Smooth Hydrangea)

Hydrangea arborescens, commonly known as Smooth Hydrangea, Wild Hydrangea, Sevenbark, or in some cases, Sheep Flower, is a species of flowering plant in the family Hydrangeaceae. It is a small- to medium-sized, multi-stemmed, deciduous shrub up to 2m tall that is native to the eastern United States.

The stem bark has a peculiar tendency to peel off in several successive thin layers with different colors, hence the common name "sevenbark". Smooth Hydrangea can spread rapidly by stolons to form colonies. This plant also acts as a pollinator plant, supporting and attracting bees and butterflies.

The variety 'Annabelle' has huge spherical white flowerbeds. Blooms every year, even after severe pruning or harsh winters.
