How to grow
Cultivation
Grow in full sun in fertile, moisture-retentive, humus-rich soil. Keep well watered in summer dry spells. Tall stems may need support (see staking: perennials). 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 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 powdery mildews, leaf spot, verticillium wilt and virus diseases
