Farfugium japonicum syn. Ligularia tussilaginea is a species of flowering plant of the family Asteraceae, also known as leopard plant, green leopard plant. It is native to streams and seashores of Japan, where it is called Tsuwabuki (石蕗).
It grows in a loose clump about 60 cm (24 in) tall and wide, spreading by rhizomes. Daisy-like yellow flowers, 2.5–5 cm (1–2 in) across, are borne in loose clusters in autumn and winter.
It 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. 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.
The cultivar 'Aureomaculatum' has gained the Royal Horticultural Society's Award of Garden Merit.
