[edit] 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.
[edit] Toxicity
Farfugium japonicum contains tumorigenic pyrrolizidine alkaloids.[1],[2]
[edit] 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]
