Seedling
2-3 weeksDelicate seedlings emerge with fine, thread-like cotyledons and minimal foliage
Keep soil warm (70-80°F) and consistently moist. Provide bright light and protect from wind. Thin seedlings to proper spacing once first true leaves appear
Vegetative
4-6 weeksPlant develops feathery, fern-like foliage with thin, branching stems. Leaves are finely divided and delicate
Maintain warmth and consistent moisture. Support plants with light staking if needed in windy locations. Avoid excessive nitrogen fertilizer which promotes foliage over seed production
Flowering
2-3 weeksSmall white, pale pink, or light purple flowers appear in delicate umbels at stem tips
Maintain consistent watering during flowering to prevent premature seed drop. Ensure adequate sun exposure for good pollination. Bees and other pollinators are beneficial
Seed Development & Maturation
3-4 weeksFlowers fade and elongated seed pods (schizocarps) develop, turning from green to brown as they mature. Each pod splits into two seeds
Reduce watering slightly as seeds mature to encourage ripening. Monitor closely for harvest timing. Seeds are ready when fully brown and aromatic
Harvest & Seed Drying
Variable (harvest + drying)Mature seed pods brown completely and are ready for cutting. Seeds must be dried thoroughly for storage
Cut entire seed heads when brown. Dry in a warm, airy location for 1-2 weeks until seeds separate easily from pods. Thresh to remove seeds from chaff

Harvest Tips
Harvest seed heads when they turn completely brown (typically 100-120 days after planting) but before pods shatter naturally. Cut entire seed heads in the morning after dew dries. Hang bundles upside down in a warm, dry location for 1-2 weeks to finish drying. Once dry, rub seed heads between hands to thresh and separate seeds from chaff. Store dried seeds in airtight containers away from light and heat
