Germination & Seedling
2-3 weeksTiny seedlings with fine needle-like cotyledons emerge within 7-14 days. Plants develop their characteristic feathery, finely-divided foliage
Keep soil consistently moist but not waterlogged during germination. Provide bright light. Thin seedlings to proper spacing once 2-3 inches tall
Vegetative Growth
3-4 weeksPlants develop bushy mounds of delicate, fern-like foliage 12-30 inches tall depending on variety. No flowers yet; energy goes into establishing root system and leaf growth
Water regularly during this phase until established. Pinch back growing tips if a bushier plant is desired. Reduce watering as roots develop
Bud Formation & Flowering
8-12 weeks or longerFlower buds appear at branch tips in bright yellow, deep red, maroon, or bicolored combinations. Flowers open progressively, creating a long display of small (1-2 inch) daisy-like blooms
Deadhead spent flowers regularly to encourage continuous blooming. Reduce supplemental watering; drought actually triggers more prolific flowering. Minimal fertilizer needed
Peak Bloom & Decline
6-10 weeksMaximum flower production in mid to late summer through frost. As days shorten and temperatures cool in fall, flowering gradually decreases
Continue deadheading if prolonged bloom is desired, or allow flowers to fade for seed production. Monitor for any pest issues. Reduce watering further
Seed Production & End of Season
4-6 weeks until frostIf flowers are left undeadheaded, distinctive cone-shaped seed heads develop and mature to brown. Plants may self-seed for next year. Foliage yellows and plants die back with frost
Allow seed heads to remain for wildlife food and self-seeding, or collect seeds for storage. Pull plants after frost, or leave for winter interest and spring cleanup

Harvest Tips
Harvest flowers for cutting in early morning when they're fully open. Cut stems just above a leaf node to encourage branching and more blooms. Flowers typically last 5-7 days in a vase. For seeds, allow flowers to fade and seed heads to dry on the plant until brown, then collect and store in a cool, dry place for next season's sowing
