Germination & Seedling
7-14 days germination; 3-4 weeks to first true leavesTiny seedlings emerge with cotyledons (seed leaves). First true leaves appear delicate and narrow.
Keep soil moist but not soggy. Provide bright light and good air circulation. Thin seedlings to 2-3 inches apart if needed. Maintain 65-70°F temperature for best germination.
Vegetative Growth
4-6 weeksPlant develops bushy foliage with lance-shaped leaves arranged in a rosette. Stems elongate and become sturdy.
Maintain consistent moisture and regular feeding with diluted balanced fertilizer every 2-3 weeks. Pinch growing tips if needed to encourage bushiness. Ensure good air circulation.
Bud Formation
2-3 weeksFlower stems elongate and buds form at terminal points. Plants reach 18-30 inches tall depending on variety.
Continue regular watering and fertilizing. Support tall varieties with stakes if needed. Remove any lower yellowing leaves for better air flow.
Flowering
8-12 weeks or longer with regular deadheadingDistinctive pincushion-shaped flowers bloom in layers, opening progressively from bottom to top. Blooms attract butterflies and pollinators.
Deadhead spent flowers regularly to promote continuous blooming. Water at soil level only. Provide afternoon shade in very hot climates. Cut for arrangements to encourage more flowering.
Seed Production & End of Season
2-4 weeksIf not deadheaded, flowers fade and develop seed heads that birds enjoy. Foliage may decline in late summer heat.
Allow some flowers to mature for seeds if you want self-seeding next year. Collect seed heads when dry and brown. Remove spent plants after frost.

Harvest Tips
Cut flowers in early morning when stems are hydrated. Blooms last 8-10 days in a vase. Cut just below the flower head when the bloom is fully open or slightly before for longer vase life. Regular cutting encourages more flower production. For seed collection, allow flowers to dry on the plant until brown and papery, then remove seed heads and dry indoors.
