How to Grow

Cultivation

Will thrive in most soils, as long as there is good drainage, but a moderately fertile, humus-rich soil that is not too acidic is ideal. Position in full sun and provide support, as stems can flop after heavy rain (see staking perennials)

Propagation

Propagate by division in spring, or by root cuttings in late autumn and early winter. Plants may produce seed, but seedlings may not be true to the parent plant

Suggested planting locations and garden types

  • Cottage and informal garden
  • Flower borders and beds

Pruning

Cut spent flowering stems back to the ground, unless seed heads are required. Cut back foliage as it fades in summer

Pests

May be susceptible to aphids

Diseases

May be susceptible to downy mildews, powdery mildews, fungal wilts and verticillium wilt
