In the garden

Cimicifuga simplex var. ramosa sits in the Ranunculaceae and originates from temperate regions of eastern Asia, including Kamchatka, Sakhalin, Siberia, western China, Manchuria, Mongolia, Korea and Japan. As a herbaceous perennial it reaches about 1.5 m, offering upright presence in shaded parts of the garden. Plant where light is limited: partial to full shade suits it best. Soil may be sandy, loamy or clay provided it remains moist yet drains away excess water; avoid sites that become bone dry in summer. The rating H7 indicates it is fully hardy across the UK and will withstand winter frosts that correspond with USDA zones 4–8. In a UK garden place specimens in a shaded border, a woodland edge or beneath trees where soil moisture is steady. Its height makes it useful for mid to rear layers of a shade border, giving vertical structure without requiring sun. Allow plants to establish in situ and expect individuals to attain around 1.5 m tall when conditions remain consistently moist and shaded.
