Growing Information
How to plant:
Propagate by
seed,
division or separation
- Sow seeds in spring or divide plants in late summer.
Maintenance and care:
May require staking. Deadhead faded flower stalks to keep plants looking tidy (they tend to fade out late in the season) and to prevent reseeding. Some reseeding may be desirable as plants tend to be short-lived in warm areas.
Cutting back plants to basal foliage after flowering may produce some later reblooming.
Plants seldom need division. Divide in late summer as needed to propagate.
