Planting & Care
  • Slow to emerge in spring
  • Deadheading will prolong bloom and improve appearance
  • Easily grown from seed, flowering the second year after sowing
  • Division is tricky because of the fragile, stringy root system
  • Best left undisturbed once established
  • Taller varieties are often floppy and require staking
  • Cutting plants back by half in May will result in fuller plants with sturdier stems
