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
Propagate by seed or by basal softwood cuttings in spring, or by division in spring or late autumn
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
May be susceptible to stem and bulb eelworm, tortrix moth, slugs and snails
May be susceptible to leaf spot, Verticillium wilt and virus diseases
