Germination & Seedling
2-3 weeksTiny seedlings with fine, feathery foliage emerge within 7-14 days. First true leaves are deeply lobed and delicate.
Keep soil consistently moist but not waterlogged. Thin seedlings to 9 inches apart early. Avoid overwatering which promotes damping off.
Vegetative Growth
3-4 weeksPlant develops a rosette of fern-like, blue-green foliage. Stems elongate and branch. Buds begin to form at stem tips.
Ensure good air circulation to prevent disease. Minimal fertilizer needed; too much nitrogen reduces flowering. Stake taller plants if needed in windy locations.
Budding & Flowering
4-6 weeksDistinctive nodding buds appear, encased in hairy sepals. Buds open in morning to reveal crumpled scarlet petals with black basal blotches.
Deadhead spent flowers to encourage continued blooming. Water at soil level to keep petals dry. Peak bloom in cool weather.
Seed Development & Maturation
2-3 weeksAfter petal drop, seed pods (capsules) develop, becoming smooth and rounded. Pods mature from green to tan/brown.
Allow some flowers to remain unpicked for self-seeding. Harvest seed pods when tan and dry for seed collection. Remove plants if volunteer seedlings are undesirable next year.
Decline & End of Season
VariableAs temperatures warm (late spring/summer) or in fall, plants decline. Foliage yellows and stems weaken.
This is a cool-season annual; it declines in hot weather. In mild climates, fall sowing for winter/spring flowers extends the season. Remove spent plants.
