"Saffron costs what it costs because every thread was picked by hand from a flower that blooms once a year for two weeks.

What Saffron Crocus Requires
Crocus sativus (saffron crocus) blooms in autumn, not spring like most crocuses. Each flower produces three red stigmas — the saffron threads. A single plant produces 3 threads per season. You need about 50 to 75 corms for a meaningful harvest (enough saffron for several dishes). Corms require: well-draining soil, full sun, a dry summer dormancy, and cold winters to vernalize (trigger flowering). They multiply over years if not dug up.
3Threads Per Flower
Plantin September
Plant Corms in Well-Draining Soil
Plant 4 inches deep, 4 to 6 inches apart, pointed end up, in full sun.
Plant Corms in Well-Draining Soil
Plant saffron corms in September (Northern Hemisphere) in full-sun well-draining soil. Amend heavy clay with grit and compost. Plant 4 inches deep, 4 to 6 inches apart, pointed end upward. Container planting: use a shallow pot (6 to 8 inches deep) with fast-draining succulent mix. Do not water after planting — wait for first fall rains or withhold water until you see leaf tips emerge.
Manage Summer Dormancy
Stop watering when foliage dies back in spring and keep corms dry until fall.
Manage Summer Dormancy
Saffron crocus corms require a dry summer dormancy — the most common failure point. After the foliage yellows and dies back in late spring, stop watering completely. If in containers, move them to a dry covered location. Resume watering in late August to early September to break dormancy and trigger flowering. In humid climates, corms may rot if left in moist soil through summer.
Harvest on the Day Flowers Open
Pick stigmas the morning flowers open — they degrade within hours.
Harvest on the Day Flowers Open
Saffron crocus flowers open in October to November. The three red stigmas must be harvested on the day the flower opens — within hours of opening. Pick the stigmas by hand, tweezers, or small scissors. Lay on a paper towel and dry in a warm oven (150°F) for 15 to 20 minutes or air dry for 24 to 48 hours. Store in an airtight container away from light.
What You Need
Crocus sativus corms — buy in August for fall planting
Well-draining sandy or gritty soil
Full-sun location — 6 hours minimum
50 to 75 corms for a meaningful harvest
Small tweezers for stigma harvesting
Airtight container for storing dried saffron
Crocus sativus Is the Only Saffron Species Other autumn-blooming crocuses can be toxic — ensure you plant Crocus sativus specifically, not Colchicum autumnale (meadow saffron) which looks similar and is poisonous. All three stigmas in C. sativus are red and trumpet-shaped. Colchicum has 6 stamens; C. sativus has 3 stigmas and 3 stamens.
"Plant fifty corms this fall. In ten years you will have five hundred. The math works slowly in your favor.
