Propagation

Propagate by seed sown in pots in an open frame as soon as seed is ripe. Propagate by taking root cuttings in winter

Suggested planting locations and garden types
  • Patio and container plants
  • Gravel garden
  • Rock garden
Pruning

Leave faded flowers as seedheads are an attractive feature
