Flowering
6-10 weeksDelicate bright blue flowers with pink and white centers bloom in clusters on upright stems above foliage.
Deadhead spent flowers to encourage more blooms and prevent excessive self-seeding. Water during dry periods. Flowers typically appear in spring and early summer.
Seed Production & Dormancy
4-8 weeks before dormancyFlowers fade and develop small round seed capsules. Plant begins to decline in heat. Dies back in winter in colder zones.
