Stigma branches of the pistil of the true crocus flower. These are 2.5-4.5 cm long and are harvested as saffron. Collection time: spring. Saffron is known as a spice and because of its color as a coloring agent for food. As a children's song says: "Saffron makes the cake gel".
Saffron is harvested by hand: the tips of the pistils with the saffron threads attached are pinched off the flowers. For 500 g of saffron (dry weight), 200,000 to 400,000 stigmas are needed, which explains the high price of saffron threads, one of the most expensive spices ("red gold").
The quality of saffron (Croci stigma) is defined in the German Pharmaceutical Codex (DAC).
