Saffron crocus is a way of appearing in the fall of their purple flowers which are won – the saffron. This species is a triploid mutant of the cartwrightianus on the Aegean islands and Crete Crocus domiciled. It is three times because of the chromosome set infertile and can only be propagated vegetatively by tuber division. The ancestor of Crocus cartwrightianus has significantly shorter, but also aromatic stigmas.
Each crocus flower contains three stigmas in a branching style. Only this sweet-smelling aromatic stigmas are dried as a spice. To gain a kilogram of them, one needs about 150,000 flowers from an area of approximately 1,000 square feet. The harvest is done by hand, a picker will create 60 to 80 grams a day. Furthermore, saffron once per year in the fall (and only for about two weeks) is flourishing. Why saffron is the world’s most expensive spices.
