Saffron
Harvesting

The high retail value of saffron is maintained on world markets because of labour-intensive harvesting methods, which require some 440,000 hand-picked saffron stigmas per kilogram (200,000 stigmas/lb) – equivalently, 150,000 crocus flowers per kilogram (70,000 flowers/lb). Forty hours of labour are needed to pick 150,000 flowers.

One freshly picked crocus flower yields on average 30 mg of fresh saffron or 7 mg dried; roughly 150 flowers yield 1 g (1 ⁄ 32 oz) of dry saffron threads; to produce 12 g (7 ⁄ 16 oz) of dried saffron, 450 g (1 lb) of flowers are needed; the yield of dried spice from fresh saffron is only 13 g/kg (0.2 oz/lb).
