Farfugium japonicum is a plant of the family Asteraceae, also known as leopard plant, green leopard plant, and ligularia.
Farfugium japonicum is native to rocky coastal cliffs of Japan, Korea, and Taiwan. Most cultivars have shiny green leaves variegated with irregular creamy white or yellow markings, which are leathery and large, 4-10 in (10.2-25.4 cm) across, rounded or kidney shaped, with wavy or toothed margins, held aloft on long stalks, and they are evergreen.
Farfugium japonicum grows in a loose clump about 2 ft (0.6 m) tall and wide spreading by rhizomes. Daisy-like yellow flowers, 1-2 in (2.5-5.1 cm) across, are borne in loose clusters.
Farfugium japonicum contains tumorigenic pyrrolizidine alkaloids.,
