Ragged Robin (Lychnis flos-cuculi)

Branched stems bear opposite, lance-shaped leaves. Clusters of star-shaped deep rose-pink flowers, each petal deeply cut into 4 narrow segments, appear in late spring and early summer. It prefers to be in moist soil rather than in the water.

Little maintenance is required. Trim just above the water surface after foliage has died back in Autumn to tidy.

Plant in full sun to partial shade between 0cm and 1cm deep.

• Flowering period: May to August
