How to grow

Cultivation

Grow in humus-rich well-drained soil in full sun; poor drainage in winter will lead to losses. A dry mulch in winter is advisable in very cold areas. Leave plants to develop into substantial clumps as they resent disturbance

Propagation

Propagate by seed in spring, but may need a cold spell before it will germinate. Root cuttings can be taken in late autumn or early winter. Propagate by division in spring but this can be unreliable as they resent disturbance
