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 (called Tsuwabuki, written 石蕗), Korea, and Taiwan.
Description
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.
Some 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. Others are an even green without the white or yellow markings.
Toxicity
Farfugium japonicum contains tumorigenic pyrrolizidine alkaloids.[1],[2]
Cultivation
Farfugium japonicum is grown as an ornamental plant for garden planting and containers. The variegated cultivars are often used to brighten shade garden settings. Farfugium japonicum var. giganteum is a very large leaved selection. [3]
