Features

Often used as background plant or specimen plants in the cutting garden. Long-time garden plant that has the ability to reseed and come back for years.

Culture

Full sun, and well-drained soil. Technically a biennial but if planted early they are best treated as annuals. They may come back in the spring or new plants may sprout from the seeds.

Cultivars

  • 'Indian Spring'
  • 'Nigrita'
  • 'Chaters Purple' (double)
  • 'Summer Carnival'

Notes

May need staking to prevent wind damage. Pinch main stem early in the season to produce bushier, shorter plants less likely to need staking.
