About

Trollius stenopetalus is a perennial that bears narrow, globe-shaped flowers. It comes from Siberia, Far East Russia, China and Japan and belongs to the Ranunculaceae family. In the UK it flowers from May to July and prefers moist, neutral to slightly acidic, well-drained soil in full sun or partial shade. All parts are toxic if ingested, so avoid siting it where children or livestock may reach it.

In the garden

Trollius stenopetalus is a temperate perennial from Siberia, Far East Russia, China and Japan and sits within the Ranunculaceae family. Its narrow-petaled, rounded blooms appear in late spring and early summer, offering a clear flowering window from May to July. Plant into moist, well-drained soil that is neutral to slightly acidic and give it full sun or partial shade; plants will tolerate north, east, west or south-facing positions. It is rated H5 — hardy in most UK gardens — and will withstand sites from sheltered to exposed. Keep soil reliably moist rather than bone-dry; the species performs best where soil moisture is steady. Use Trollius stenopetalus at the back of perennial borders, alongside streams or in water-garden margins, and in naturalistic plantings where consistent moisture is available. Because every part of the plant is toxic if eaten, avoid placing it within reach of livestock or close to vegetable beds used for food crops. Its defined May–July flowering season makes it useful where a predictable late-spring to early-summer display is required.
