Dormancy & Corm Preparation
4-6 weeksSaffron corms are planted in mid-to-late summer. The corms remain dormant underground, developing roots during warm months.
Select healthy, disease-free corms. Store in cool, dry conditions before planting. Prepare soil thoroughly with drainage amendments.
Root Development & Growth
4-6 weeksAs autumn temperatures cool, roots extend into soil and green foliage begins to emerge. Thin grass-like leaves appear above ground.
Ensure good drainage. Water moderately if rainfall is sparse. Avoid disturbing newly planted corms. Monitor for fungal issues.
Flowering
2-3 weeks of flowering windowDelicate purple flowers with yellow centers and three red stigmas bloom in autumn (October-November in Northern Hemisphere). Each corm produces 1-4 flowers.
Hand-harvest stigmas as flowers open. Harvest in early morning when flowers have just opened. Be gentle; stigmas are extremely fragile.
Harvest & Drying
2-3 weeks drying timeRed stigmas are carefully removed from flowers and dried to concentrate flavor and color. Drying reduces weight to 1/6th of fresh weight.
Harvest stigmas immediately after removal using tweezers. Dry on paper in a cool, dark location for 1-2 weeks. Store in airtight container away from light.
Post-Harvest & Dormancy
4-6 weeksAfter flowering, foliage continues to mature and develop nutrients for next year's bloom. Foliage yellows and dies back as temperatures warm.
Allow leaves to fully mature and die back naturally—do not cut prematurely. Reduce watering. Foliage feeds the corm for next season's flowers.

Harvest Tips
Harvest stigmas as soon as flowers open, ideally in early morning. Use fine-tipped tweezers to gently pull the three red threads from the flower center. Fresh stigmas must be dried slowly in a cool, dark, well-ventilated area for 1-2 weeks until brittle. Store dried saffron in airtight containers away from light and heat. One ounce of dried saffron requires approximately 150 flowers, making hand-harvesting extremely labor-intensive.
Fun Facts
- 🌱 Saffron is the world's most expensive spice by weight, often costing $10-15 per gram. It takes approximately 150 flowers to produce just one gram of dried saffron, making it more precious than gold by weight.
- 🌱 Each Crocus sativus flower contains only three delicate red stigmas (the female reproductive parts), and each must be hand-harvested individually using tweezers, contributing to its high cost and labor intensity.
- 🌱 Saffron has been valued for over 3,000 years. Ancient civilizations used it in royal ceremonies, as a dye, and in traditional medicine. Iran currently produces about 90% of the world's saffron supply, particularly in the Khorasan province.
