Hydrangea Root
Hydrangea root was used by the American Indian (esp. Cherokee) as a remedy for kidney and bladder stones and is currently being studied as a treatment for malaria. ‘Annabelle’ and ‘Grandiflora’ are commonly available cultivars. Propagation is best by softwood cuttings in May-June or by division in late winter or early spring. Smooth Hydrangea is hardy in zones 4-9.
