A popular cultivar among garden designers, this lovely grannys bonnet has beautiful, fully double, spur-less purple-black flowers in late spring above fern-like green leaves. It looks gorgeous with other black flowers and is equally at home in cottage-garden schemes or among grasses. It thrives best in soil that retains moisture over the summer. It is easy to grow and quite short-lived, but self-seeds freely, though rarely to nuisance level. - Garden care: Lift and divide large clumps in early spring and apply a generous 5-7cm (2-3in) 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. Deadhead to prolong flowering. Contact with the sap may cause skin irritation.
