Abstract Root and rhizome production of goldenseal (Hydrastis canadensis) was measured annually from 1996 to 2002 under shade in Waikato, New Zealand. Root and rhizome production increased annually to 60–70 g dry matter (DM)/plant after 6 years, giving a root:rhizome DM yield of 5500 kg/ha. Initial growth was dominated by the roots but by the fifth and sixth year, the root:rhizome ratio remained constant at 1.2. After 6 years, approximately 84% of the root and rhizome mass was in the first 50… Expand
