- No pruning required. Remove dead leaves and flower stems before new growth starts in spring
- Propagation
- Propagate by division in early spring when clumps become congested or Propagate by seed sown in containers in a cold frame as soon as ripe
- Pest resistance
- May be susceptible to red spider mite
- Disease resistance
- Generally disease-free
