A prominent component of the amazing "megaherb" communities of the subantarctic islands south of New Zealand, including Macquarie Island at 54°S, this stunning plant from the Aralia or ivy family (Araliaceae) has large, circular leaves that are toothed around the edges. Its flower stalk can grow to about 1.8 m (6 ft.) tall. In cultivation it will do best in cool or cold temperate, oceanic climates. It does not like high summer temperatures, especially hot and humid conditions, but is otherwise easy to grow. Seeds may benefit from cold stratification for a few weeks after sowing.
