Ligularia dentata (summer ragwort or leopardplant[3]) is a species of flowering plant in the genus Ligularia and the family Asteraceae, native to China and Japan.

Description

It is a robust herbaceous perennial growing to 1–1.5 m (3–5 ft) tall by 1 m (3 ft) wide.[4] The dark green leaves are large, long-stalked, leathery, cordate-based, and very rounded, with serrated edges (hence the Latin dentata meaning "toothed")[5] . Orange-yellow daisy-like composite flowers bloom on thick red, mostly leafless stalks, rising above the foliage in early summer.

Cultivation

Ligularia dentata is grown as an ornamental plant, chosen as much for its bold foliage as its flowers.[6] It is used as a round-leaved accent plant or massed planting in moist sun and partial shade garden settings, and in containers. Cultivars include 'Desdemona' and 'Othello'. Selections with cream colour spotted foliage (polka dots) are also grown.

Toxicity
