Crocus sativus
Also called Saffron, Autumn Crocus, Italian Crocus
Saffron crocus is an autumn-flowering cormous perennial grown for the red stigmas that are dried to make the spice saffron; it is unknown in the wild and propagated by corms.
Crocus sativus, commonly known as saffron crocus or autumn crocus, is a species of flowering plant in the iris family Iridaceae. A cormous autumn-flowering cultivated perennial, unknown in the wild, it is best known for the culinary use of its floral stigmas as the spice saffron. Human cultivation of saffron crocus and the trade and use of saffron have endured for more than 3,500 years and span different cultures, continents, and civilizations.
As a sterile triploid, C. sativus is unknown in the wild and relies upon manual vegetative multiplication for its continued propagation. Because all cultured individuals of this plant are clonal, there is minimal genetic diversity from the single domestication event, making it quite hard to find cultivars with new, potentially beneficial properties, let alone combine them by breeding. Cultivars of saffron are nevertheless produced by a number of means:
Clonal selection. Any plant with a desirable mutation is kept and further grown. This is the traditional approach.
The stigmas of the flower are used as the culinary spice saffron. It is also used for health purposes, especially in traditional Asian medicine - owing to biologically active chemical compounds (mainly alkaloids, anthocyanins, carotenoids, flavonoid, phenolic, saponins, and terpenoids) saffron causes among others mood-enhancing effect (including persons with major depressive disorder). Depending on the size of harvested stigmas, the flowers of between 50,000 and 75,000 individual plants are required to produce about 1 pound of saffron; each corm produces only one or two flowers, and each flower produces only three stigmas. Stigmas should be harvested mid-morning when the flowers are fully opened. Saffron crocus can be used as an ornamental.
