Ligularia, commonly known as leopard plant, is a genus of herbaceous perennial plants in the family Asteraceae (sunflower family), placed in the tribe Senecioneae (groundsel tribe) and the order Asterales. It was described by the French botanist Alexandre Henri Gabriel de Cassini (Cass.) in 1809.
The genus comprises approximately 120 to 140 species of robust, clump-forming perennials. Plants produce bold, often large basal leaves and tall flowering stems bearing clusters of composite flower heads in shades of yellow or orange, with brown or yellow central disc florets and distinctive strap-shaped ray florets — the latter being the source of the genus name, from the Latin ligula, meaning "strap." The prominent ray florets give the blooms their daisy-like appearance.
Ligularia is predominantly an Asian genus, with more than half of its species endemic to China, where it is particularly diverse across montane and subalpine regions. The natural range extends across central and eastern Asia — including Japan, Korea, the Himalayas, and Siberia — with a smaller number of species reaching into Europe. Plants are characteristic of damp, fertile habitats such as streambanks, wet meadows, boggy ground, and shaded woodland margins.
Several species and their cultivars are widely grown as ornamental garden plants, valued for their striking foliage and late-season flowers. Ligularia dentata 'Britt Marie Crawford', L. × hessei 'Gregynog Gold', and L. przewalskii 'The Rocket' have each received the Royal Horticultural Society's Award of Garden Merit. They perform best in fertile, moist soil with full sun or partial midday shade, making them popular choices for waterside planting and shade gardens.
Etymology
The genus name Ligularia derives from the Latin ligula, meaning "strap" or "small tongue," referring to the distinctive strap-shaped ray florets of its composite flower heads. The name was established by the French botanist Alexandre Henri Gabriel de Cassini in 1809.
Distribution
Ligularia is native to damp habitats across central and eastern Asia, with the greatest diversity in China, where more than half of the approximately 120–140 species are endemic. The range extends through Japan, Korea, Siberia, and the Himalayan region, with a small number of species also occurring in Europe. Plants typically grow along streambanks, in wet meadows, boggy ground, and moist woodland margins.
Cultivation
Ligularia species are cultivated as ornamental perennials in gardens worldwide. They grow best in fertile, consistently moist soil, preferring full sun with some protection from intense midday heat, or dappled shade. They are particularly effective in waterside and bog garden settings. Several cultivars have received the Royal Horticultural Society's Award of Garden Merit, including L. dentata 'Britt Marie Crawford', L. × hessei 'Gregynog Gold', and L. przewalskii 'The Rocket'.
