Growth Stages
Germination & Seedling
2-3 weeksTiny seedlings with thin cotyledons emerge in 7-10 days. First true leaves are finely divided, resembling delicate fern-like foliage.
Keep soil moist but not waterlogged. Provide bright light to prevent legginess. Thin seedlings to prevent damping-off disease.
Vegetative Growth
4-6 weeksPlant develops increasingly bushy form with multiple stems and feathery, bipinnate leaves. No flower buds visible yet.
Pinch back growing tips when seedlings are 6 inches tall to encourage bushier growth and more branching. Continue regular watering.
Bud Formation
2-3 weeksFlower buds appear at branch tips as small, tightly-closed structures on elongated stems. Plant reaches near-full size.
Reduce nitrogen fertilizer to encourage flowering rather than leafy growth. Maintain consistent moisture; avoid drought stress.
Flowering
8-12 weeks or until frostLarge, daisy-like blooms open in pink, white, or crimson colors with yellow-gold centers. Flowers are 2-4 inches across on tall, airy stems.
Deadhead spent flowers regularly to promote continuous blooming throughout season. Provide stakes for tall varieties if needed in windy areas.
Seed Maturation & End of Season
2-4 weeks before frost or end of seasonFlowers fade and dry; seed pods develop. Foliage may become thin as plant channels energy into seed production.
Stop deadheading if you want self-seeding next year. Allow flowers to dry on plant; collect seeds when fully brown and papery. Plants die with first frost in cold climates.

Harvest Tips
Cut flowers in early morning when fully open for longest vase life (7-10 days). Use sharp scissors or pruners and remove lower leaves from stems. Deadhead spent blooms regularly to encourage more flowers throughout the season. For seed collection, allow final flowers to dry completely on the plant (brown and papery), then cut stems and collect seeds for next year.
