How to grow

Cultivation

Grow in full sun in fertile, moisture-retentive, humus-rich soil. Keep well watered in summer dry spells. Divide every two to three years to maintain vigour

Propagation

Propagate by seed or by basal softwood cuttings in spring, or by division in spring or late autumn

Suggested planting locations and garden types

Coastal
Cottage and informal garden
Prairie planting
Wildlife gardens
Cut flowers
Flower borders and beds

Pruning

No pruning required, but chopping or pinching out a section of plants in late spring can result in bushier growth that flowers slightly later, hiding leggy stems. Deadheading will also prolong flowering

Pests

May be susceptible to stem and bulb eelworm, tortrix moth, slugs and snails

Diseases

May be susceptible to leaf spot, Verticillium wilt and virus diseases
