How to plant:
Maintenance and care:
division or separation
- Sow seeds as soon as they are ripe. Self-sows readily. Some varieties are hybrids and will not breed true.
Make stem cuttings in midsummer.
In fall, divide new rosettes that form to the side of parent plants.
Deadhead to improve appearance and encourage rebloom. Because plants are short-lived some reseeding is desirable.
Pinch back if you want bushier, more compact plants.
Keep soil moist during summer dry spells. Afternoon shade is beneficial if soil is dry.
Do not cut plants back in fall. Mulch lightly. While moisture-loving during the growing season, excess moisture can kill plants overwinter.
Divide plants every 2 or 3 years. Allow plants to self-seed to replace short-lived plants.
