Masses of pompom like pale green and rose red flowers in late spring and early summer above deeply divided fern-like leaves. This charming columbine is guaranteed to create a startling mid border display for a moist well-drained site. Although short lived if grown in isolation the plant self seeds freely producing seedlings that are true to type.

• 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. Contact with the sap may cause skin irritation.
