Small, papery, plum-coloured, pincushion-like flowers surrounded by a ruff of wine-tinted bracts, are produced from June to August above deeply lobed, dark green leaves.

    Incorporate plenty of organic matter when planting and water well in dry weather, especially newly established plants. Lift and divide large clumps in early spring and apply a generous 5-7cm mulch of well-rotted manure or garden compost around the plant. Divided specimens may take some time to establish since they don't like having their roots disturbed.
