1795 Saffron Crocus sativus Illustration
1795 Illustration from Bertuch "Bilderbuch Fur Kinder". Saffron - a spice from the stigma of the flower of Crocus sativus - the "saffron crocus". The styles and stigmas,called threads,are collected and dried to be used as a seasoning and food colouring. Worth more than its weight in gold. Amongst the world's costliest spices. It is a genetically monomorphic clone originating in Eurasia (probably Greece) and taken worldwide. It is a "self-incompatible" triploid and male sterile so all propagation is by vegetative multiplication via manual "divide-and-set" of a starter clone or by interspecific hybridisation. It may have emerged via plant breeding selecting for elongated stigmas,in late Bronze Age Crete. Its properties are from chemicals picrocrocin and safranal and a carotenoid pigment,crocin. There is evidence from old cuneiform texts that it has been traded for over 4000 years
