Flowering
4-8 weeksCharacteristic spikes of tiny tubular flowers open sequentially from bottom to top, creating a dramatic color display over several weeks.
Deadhead spent flowers to encourage continued bloom and extend flowering period. Water at soil level to avoid wetting flowers. Cut for fresh arrangements.
Seed Set & Dormancy
6-8 weeks into dormancyAfter flowering, seed heads develop and dry. Foliage begins to decline as plants prepare for winter dormancy.
Leave seed heads for wildlife and winter interest, or remove for neatness. Stop fertilizing in late summer. Reduce watering. Cut back stems in fall or early spring.
