About
Trollius riederianus is a clump-forming herbaceous perennial in the Ranunculaceae that favours moist or poorly drained ground and flowers from May to July. It produces rounded, globe-like blooms above deciduous foliage. Plant in clay or loam that remains damp, in full sun or partial shade. It tolerates a wide soil pH range and will survive UK winters down to fully hardy conditions.

In the garden
Trollius riederianus sits in the buttercup family and forms neat clumps of foliage that die back after the season. Flowering runs from May to July, when globe-like blooms are held above a low mound of leaves. The plant suits sites where the soil stays damp, including poorly drained hollows or the margins of boggy features. Choose a position in full sun or partial shade on clay or loam soils; the species tolerates acid to alkaline conditions. It copes with both exposed and sheltered situations and is rated H7, meaning it is fully hardy across the UK and will withstand typical winter conditions without special protection. Use Trollius riederianus toward the back of a flower border, in cottage and informal plantings, or at the damp edge of a wildflower meadow where its seasonal display can be appreciated. Because it is clump-forming and deciduous, allow the foliage to die back naturally before removing it to reveal the following season's regrowth, and site it where its May–July flowering period complements other moisture-loving perennials.
