Seedling
2-3 weeksTiny cotyledons emerge with thin green stems and small linear leaves forming low rosettes
Keep soil consistently moist but not waterlogged. Provide bright light to prevent leggy growth. Thin seedlings to proper spacing when 2-3 inches tall.
Vegetative Growth
3-4 weeksCompact mounding plant develops ferny, fine-textured foliage with increasing stem branching; no buds yet visible
Maintain moderate moisture and full sun exposure. Pinch growing tips when 4-6 inches tall to encourage bushier growth and more flower sites. No fertilizer needed if soil is decent; excess nitrogen reduces flowering.
Budding
2-3 weeksTight flower buds form at stem tips with distinctive spiky sepals; plant reaches maximum height of 12-18 inches
Continue regular but moderate watering. Do not overwater at this stage as it can cause budding delays. Ensure full sun continues.
Flowering
6-12 weeks or more with deadheadingDouble rose-pink blooms open from late spring through fall; flowers are ruffled, pompom-like with tightly packed petals
Deadhead spent flowers weekly to promote continuous blooming throughout the season. Provide consistent water during peak heat. Fertilize monthly with balanced fertilizer if desired for sustained production.
Seed Maturation
3-4 weeks after bloom fadesIf flowers are left undeadheaded, seed heads develop with hard, elongated seeds contained within papery sepals; flowers fade to pale pink-tan
Allow select flowers to mature if collecting seeds for next season. Cut and dry seedheads indoors. Save dried heads in paper bags in cool, dry location.

Harvest Tips
Harvest flowers in early morning after dew dries for longest vase life. Cut stems at least 8-10 inches long just as outer petals begin to open. Double blooms last 5-7 days in a vase with fresh, cool water. Deadhead regularly (every 2-3 days) to encourage more blooms throughout the season. For seed saving, allow a few flowers to fully mature, then harvest when seed pods turn brown and dry, typically 3-4 weeks after bloom.
