Seven Barks

Seven Barks

There are about 80 species of deciduous and evergreen shrubs, small trees, and root climbers in this genus, which occurs in woodlands in E Asia and N and S America. Many hydrangeas are grown for their showy floral clusters. Hydrangea arborescens is not especially ornamental but it has some fine subspecies and cultivars. The uses of H. arborescens were known to native N Americans, notably the Cherokees, who used it to treat urinary stones. It was adopted by settlers and much used by Physiomedical herbalists during the 19th century. Hydrangea comes from the Greek hydor, "water" and angos "jar", referring to the cup-shaped fruits.

Open, deciduous shrub with long-stalked, broadly ovate leaves to 18cm (7in) long. Off-white, fertile flowers and creamy-white sterile flowers are borne in corymbs 5-15cm (2-6in) across, in summer.
