Seed & Germination
1-2 weeksTiny seeds require light and warm temperatures (60-75°F) to germinate.
Surface sow on moist seed-starting mix. Keep soil lightly moist, not waterlogged. Germination occurs in 7-14 days. Provide grow lights or bright windowsill.
Seedling
3-4 weeksSmall plants with fine, thread-like emerging foliage develop true leaves with the characteristic feathery texture.
Thin seedlings to 6-8 inches apart. Keep soil moist but not soggy. Once true leaves develop, gradually reduce watering. No fertilizer needed.
Vegetative Growth
4-6 weeks (or until transplanting outdoors)Plant develops a compact mound of dense, finely divided silvery-green foliage; no flowers yet.
Transplant to 3-4 inch pots when 2-3 inches tall. Harden off gradually before planting outdoors. Space 12 inches apart. Minimal watering; allow drying between waterings.
Flowering & Blooming
June-October (4-5 months)Flat-topped flower clusters (corymbs) in red, pink, yellow, white, or coral colors emerge on stiff stems; blooms prolifically.
Deadhead spent flowers to encourage continuous blooming through fall. Do not fertilize; excess nitrogen reduces flowering. Water only during drought.
Senescence & Winter Dormancy
November-MarchFlowers fade, foliage may brown or die back depending on climate; plant prepares for dormancy.
Cut back dead foliage in fall or spring (spring in very cold climates). Leave seed heads in winter for wildlife and visual interest if desired. No watering needed.

Harvest Tips
For fresh flowers, cut stems in early morning when flowers are fully open but colors are most vibrant. Deadhead regularly to extend blooming season through fall.
