Germination & Seedling
7-14 daysTiny seedlings emerge with delicate cotyledons and first true leaves. Very small and fragile-looking.
Keep soil consistently moist but not waterlogged. Provide bright light immediately. Thin seedlings to proper spacing once they have 2-3 true leaves. No covering needed on seeds as light aids germination.
Vegetative Growth
2-3 weeksPlant develops bushy, compact foliage with thin wiry stems and finely divided feathery leaves. Growth is rapid and lateral branching occurs naturally.
Reduce watering frequency as plant becomes established. No fertilizer needed; too much nitrogen promotes foliage over flowers. Pinch tops early if extra bushiness desired, though not necessary. Space properly to ensure air circulation.
Budding & Bloom Initiation
1-2 weeksSmall flower buds form at stem tips. Plant is now full-sized and compact, typically 12-18 inches tall.
Continue minimal watering. No fertilizer needed. Begin deadheading spent blooms if continuous flowering desired. Can lightly stake if in windy location, though rarely needed.
Flowering
8-12 weeks or until frostAbundant small daisy-like flowers in yellow, red, maroon, or bicolor patterns bloom prolifically. Plants appear covered in blooms.
Deadhead spent flowers to encourage continuous blooming throughout season. Water only during drought stress. Cut flowers last well in vases. No supplemental feeding needed.
Decline & End of Season
Variable, until first hard freezeAs temperatures cool in fall, flowering slows. Plant may become leggy or decline in appearance. Seeds mature and dry on plant if left unharvested.
Allow flowers to remain on plant if you want self-seeding next year. Collect seed pods when dry and papery for seed saving. Plant dies at first hard frost.
