Germination
1-2 weeksTiny seedlings emerge with two rounded cotyledons; seeds germinate in 7-14 days at 55-65°F
Ensure consistent moisture and bright light; avoid covering seeds. Thin seedlings to prevent crowding and fungal issues.
Seedling/Vegetative
3-4 weeksFinely divided blue-green foliage develops; plant grows low and bushy with multiple branching stems
Keep soil evenly moist but not waterlogged. Thin seedlings to spacing distance to promote air circulation. Minimal fertilization needed.
Bud Formation
2-3 weeksDistinctive nodding buds form on elongating stems; buds are enclosed in sepals that will be shed as flowers open
Reduce watering slightly; allow soil to dry between waterings. Avoid overhead watering to prevent bud rot. Tall varieties may need staking.
Flowering
4-8 weeks (succession of blooms)Papery, delicate flowers open in morning light, typically red with dark purple-black centers; flowers last 1-2 days per bloom
Deadhead spent flowers to encourage continued blooming. Provide support for tall varieties. Cut flowers early morning for arrangements.
Seed Maturation
3-4 weeksFlowers fade and petals drop; seed pods (capsules) develop and mature, turning papery and gray-brown
Allow pods to dry on plant if collecting seed. Once fully dry, pods can be harvested and seeds stored. Self-seeds readily if left unharvested.

Harvest Tips
For cut flowers, harvest in early morning when buds are just opening; cut stems at an angle and place immediately in cool water. For seed collection, allow pods to dry on the plant until papery and brown, then cut stems and invert into a bag to capture seeds. Seeds remain viable for 2-3 years when stored in cool, dry conditions.
