Plant details

Ragged robin, Lychnis flos-cuculi, is found growing naturally in damp places in Europe, Caucasus and Siberia. With an upright or spreading habit, ragged robin has blue-green, lance-shaped leaves at the base of the plant, becoming more rounded further up the stem. In summer loose, flat flower heads carry star-shaped flowers with deeply cut petals, which vary in colour from purple-pink to white.

Lychnis flos-cuculi is an understated, hardy perennial perfect for growing in damp borders, around the edge of ponds and in wildlife gardens. Plant in boggy soil in full sun to partial shade.
