How to Grow

Propagation

Propagate by seed sown at 13-21°C in early spring, or by division of offsets in spring or autumn: if already rooted, treat as mature plants; if unrooted, plant in a mix of equal parts peat-free compost and sharp sand until rooted

  • Architectural
  • City and courtyard gardens
  • Coastal
  • Gravel garden

Pruning
