The Story
Plant Bio
Crocus sativus, saffron crocus, is an autumn-flowering corm six to ten inches high. Five to eleven narrow upright leaves emerge before or with the flowers, and lilac-purple saucer-shaped blooms open in autumn, each carrying three long branched red stigmas — the saffron itself — above golden anthers.
It is a sterile cultivated plant that sets no seed and exists only because people have propagated its corms for millennia. The crop is the three red stigmas from each flower, picked by hand on the morning they open, which is why saffron is the most expensive spice by weight: roughly 150 flowers make a single gram dried.
