Seedling
2-3 weeksTiny plants with 2-4 true leaves, delicate and tender
Keep soil consistently moist but not waterlogged. Provide bright light and protect from direct sun for first week. Thin seedlings to prevent crowding.
Vegetative Growth
4-6 weeksLeafy rosettes develop with increasingly larger, lance-shaped leaves growing upright
Gradually increase sunlight exposure. Water moderately and allow some drying between waterings. Begin fertilizing every 2-3 weeks with balanced fertilizer once plants have 4-6 leaves.
Stem Elongation
3-4 weeksTall stems emerge from the center of rosettes, reaching 2-4 feet with buds forming at the tips
Support tall varieties with stakes if needed. Continue regular watering and feeding. Remove any dead or diseased leaves. Ensure adequate spacing for air circulation.
Flowering
6-10 weeks (June-September)White petals radiate from prominent golden-yellow central cones; blooms are fully open and attract pollinators
Deadhead spent flowers to encourage continued blooming. Water at soil level to keep flowers dry. Reduce fertilizer to promote blooming over leaf growth. Watch for pests.
Seed Development & Dormancy
3-4 monthsFlowers fade as central cones become large and spiky seed heads; foliage may die back in late fall
Leave seed heads on plants through fall and winter for wildlife food and self-seeding. Cut back dead stems in early spring. No fertilizer needed. Minimal watering.
