Seedling
3-4 weeksSmall rosette of narrow, hairy leaves; slow initial growth
Keep soil consistently moist but not waterlogged. Provide bright indirect light. Thin seedlings to prevent overcrowding.
Vegetative
4-6 weeksRobust basal rosette with lanceolate, dark green leaves; multiple stems emerging
Water deeply but allow soil to dry between waterings. Remove any dead foliage. Mulch lightly around plants.
Budding & Flowering
6-8 weeksTall stems (24-36 inches) crowned with unopened buds; pure white petals gradually unfold around prominent orange-gold cones
Deadhead spent flowers to encourage continued blooming. Stake tall cultivars in windy sites. Fertilize monthly with balanced fertilizer.
Peak Bloom
4-6 weeksMultiple open flowers with reflexed white petals and prominent central cones; peak attraction for butterflies and pollinators
Continue deadheading. Monitor for powdery mildew in humid conditions and apply fungicide if needed. Harvest flowers for cutting in morning.
Seed Development & Decline
2-3 months through winterFlowers fade; central cones darken and harden, forming spiky seed heads attractive to goldfinches
Leave seed heads in place for wildlife food and winter interest. Cut back stems in late fall or early spring. Divide plants every 3-4 years.
