Ragwort (Ligularia)

Ligularia is a genus of bold herbaceous perennials in the daisy family, grown for large foliage and striking flower displays. The genus includes plants with different mature sizes, leaf forms, flower colors, and growing requirements, so choose a species or cultivar that fits the site rather than assuming one profile applies to all. The [RHS profile for Ligularia](https://www.rhs.org.uk/plants/10098/ligularia-wilsoniana/details) describes the genus’ large, often lobed leaves and yellow-to-orange daisy-like flower clusters. ## Garden character Ligularias bring broad foliage and a strong vertical or mounded presence to shaded borders and woodland-style plantings. Many cultivated types produce yellow or orange flower heads above the leaves, while foliage color and mature scale vary. Kew recognizes Ligularia as a genus in the [Plants of the World Online taxonomy](https://powo.science.kew.org/taxon/urn:lsid:ipni.org:names:331719-2). ## Siting and moisture Many garden ligularias perform best in deep, rich soil that stays reliably moist, with shelter from strong drying winds. Partial shade or dappled light can help protect leaves from scorching, particularly in warm afternoon sun. Some species tolerate very wet ground, while others have different preferences; use the requirements of the selected species or cultivar when choosing exposure, spacing, and winter protection. [University of Minnesota Extension](https://extension.umn.edu/about/our-stories/news/writers-guild-article-ligularia-a-statement-in-your-garden) discusses these general moist-soil and shade preferences. ## Maintenance Keep the soil from drying during active growth, and water deeply during hot, dry periods. Remove damaged or spent foliage as needed. Where plants die back after flowering or frost, cut them back when the leaves have finished for the season. Slugs and snails can damage foliage in some gardens, so monitor young leaves and use locally appropriate controls.
