In the garden

A perennial member of the Ranunculaceae, Trollius asiaticus originates from Kazakhstan to Siberia and northern China. In cultivation it is valued for sites that stay reliably moist and for planting schemes that include damp margins or meadow-style swathes. Choose a position in full sun to partial shade and plant into a moist, rich, well-drained soil with a neutral to acidic reaction. Incorporate plenty of organic matter at planting to help the soil retain moisture, and keep the rootzone consistently damp rather than allowing it to dry out between waterings. The species is classified H5 for UK hardiness, so it will tolerate typical outdoor winters across most of the country when given suitable soil and shelter from drying winds. Trollius asiaticus works well at pond edges, in damp perennial borders and in wet meadow plantings where the site does not dry out in summer. Take care with placement around pets and children because the plant is toxic if ingested. Flowers appear from May to July.
