Seedling
2-3 weeksTiny seedlings with cotyledons emerge within 7-10 days. Plants develop their first true leaves and grow slowly at first.
Keep soil consistently moist but not waterlogged. Provide bright light. Thin seedlings to proper spacing once they have true leaves.
Vegetative Growth
3-4 weeksPlants rapidly develop multiple stems and increasing foliage. Leaves are narrow, lance-shaped, and somewhat coarse. Plant height increases from 12 to 24+ inches.
Pinch back growing tips when 6 inches tall to encourage bushier growth and more branches. Water regularly. Apply balanced fertilizer every 2-3 weeks.
Budding & Early Flowering
1-2 weeksBuds form at branch tips. Plants begin flowering while still producing new vegetative growth. First blooms appear as tight, closed buds.
Maintain consistent watering and increase phosphorus-rich fertilizer (higher middle number, e.g., 5-10-5) to encourage blooming. Deadhead spent flowers to promote continuous blooming.
Peak Flowering
4-6 weeks or until frostAbundant golden-yellow flowers with dark brown/black centers (resembling small sunflowers) blanket the plant. Flowers are 1-1.5 inches across and appear in profusion.
Continue regular deadheading for prolonged bloom. Increase watering if hot and dry. Stake tall plants if needed. Watch for pest issues in warm weather.
Seed Development & Maturity
2-4 weeks before frostIf flowers are left to mature, seed heads develop with distinctive spiky, capsule-like structures containing small black seeds. Plant appearance becomes more rangy and less floriferous.
Leave seed heads on plants for bird food and self-seeding (or harvest and dry for seeds). Reduce watering. Plant will decline as temperatures drop in fall.
