Pretty pale pink or whitish green flowers held on slender branched stems above deeply lobed mid-green leaves. This old cottage garden favourite that has been cultivated since the 16th century and works equally well in the dappled shade of a woodland edge or in a sunny but moist garden border. For an eye catching display why not combine it with pink turk's cap lilies, escallonia and a climbing rose?

• Garden care: 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 5-7 cm 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.
