The reason for the high price of saffron in Iran and the world

Saffron is the most expensive spice in the world that has ever been known and used. The high price of saffron has various reasons, such as the difficulty of the harvesting process. In this way, each saffron flower has 3 saffron stigmas, and for 1 kilo of pure saffron, you need approximately 90 kilos of saffron flowers. Many plants or summer plants have a long harvest season throughout the year, but a plant like saffron has a harvest time of two weeks to 20 days throughout the year, which is one of the reasons for the high price of saffron due to its short production period.
