Saffron is a spice derived from the flower of Crocus sativus, commonly known as the "saffron crocus". The vivid crimson stigma and styles, called threads, are collected and dried for use mainly as a seasoning and colouring agent in food. Although some doubts remain on its origin, it is believed that saffron originated in Iran. However, Greece and Mesopotamia have also been suggested as the possible region of origin of this plant. Saffron crocus slowly propagated throughout much of Eurasia and was later brought to parts of North Africa, North America, and Oceania.
Crocus is a genus of seasonal flowering plants in the family Iridaceae comprising about 100 species of perennials growing from corms. They are low growing plants, whose flower stems remain underground, that bear relatively large white, yellow, orange or purple flowers and then become dormant after flowering. Many are cultivated for their flowers, appearing in autumn, winter, or spring. The flowers close at night and in overcast weather conditions. The crocus has been known throughout recorded history, mainly as the source of saffron. Saffron is obtained from the dried stigma of Crocus sativus, an autumn-blooming species. It is valued as a spice and dyestuff, and is one of the most expensive spices in the world. Iran is the center of saffron production. Crocuses are native to woodland, scrub, and meadows from sea level to alpine tundra from the Mediterranean, through North Africa, central and southern Europe, the islands of the Aegean, the Middle East and across Central Asia to Xinjiang in western China. Crocuses may be propagated from seed or from daughter cormels formed on the corm, that eventually produce mature plants. They arrived in Europe from Turkey in the 16th century and became valued as an ornamental flowering plant.
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.
Crocus vernus is a species in Family Iridaceae, native to the Alps, the Pyrenees, and the Balkans. Its cultivars and those of Crocus flavus are used as ornamental plants. The Dutch crocuses are larger than the other cultivated crocus species. Depending on the year, Crocus vernus starts flowering about the same time or up to 2 weeks after Crocus chrysanthus starts flowering. Height: 4–6" (10–15 cm).
Crocus chrysanthus, the snow crocus or golden crocus, is a species of flowering plant of the Crocus genus in the family Iridaceae. Native to the Balkans and Turkey, it bears vivid orange-yellow bowl-shaped flowers. It has smaller corms and a smaller flower than the giant Dutch crocus, although it produces more flowers per corm than the latter. Its common name, "snow crocus", derives from its exceptionally early flowering period, blooming about two weeks before the giant crocus, and often emerging through the snow in late winter or early spring. The leaves are narrow with a silver central stripe. Height: 3–4 inches (7.6–10.2 cm).
Crocus sieberi, Sieber's crocus, also referred to as the Cretan crocus or snow crocus, is a plant of the genus Crocus in the family Iridaceae. A small, early blooming crocus, it easily naturalises, and is marked by a brilliant orange which is mostly confined to the stamens and style, fading through the bottom third of the tepal. It grows wild generally in the Balkans and Greece, especially in the island Crete. There are four subtypes: sieberi (Crete), atticus, nivalis and sublimis. Its cultivars are used as ornamental plants. Height: 3–4 inches (7.6–10.2 cm).
Crocus tommasinianus, the woodland crocus, early crocus, or Tommasini's crocus, was named after the botanist Muzio G. Spirito de Tommasini (1794-1879). It is native to Bulgaria, Hungary, Albania, and the former Yugoslavia. It is often referred to as the early or snow crocus, but these terms are shared with several other species, although C. tommasinianus is amongst the first to bloom. Multiple plants are often called tommies in the horticultural trade.
Crocus angustifolius, the cloth-of-gold crocus, is a species of flowering plant in the genus Crocus of the family Iridaceae, native to southern Ukraine and Armenia. It is a cormous perennial growing to 5 cm (2.0 in) tall and wide. The narrow grass-like leaves with silver central stripe appear in late winter or early spring. They are followed by bright yellow fragrant flowers with maroon blotches on the outer petals.
Crocus biflorus, the silvery crocus or scotch crocus, is a species of flowering plant in the genus Crocus of the family Iridaceae, native to southeastern Europe and southwestern Asia, including Italy, the Balkans, Ukraine, Turkey, Caucasus, Iraq, and Iran. It is a cormous perennial growing to 6 cm (2.4 in) tall and wide. It is a highly variable species, with flowers in shades of pale mauve or white, often with darker stripes on the outer tepals. The flowers appear early in spring.
Crocus etruscus is a species of flowering plant in the genus Crocus of the family Iridaceae, endemic to woodlands of Central Tuscany (Italy). It is a cormous perennial growing to 8 cm (3.1 in) tall. The lilac flowers with purple veining and prominent orange stigmas appear in early spring.
Crocus versicolor is a species of flowering plant in the genus Crocus of the family Iridaceae, found in southeast France, Monaco, and northwestern Italy.

Crocus nudiflorus is a species of flowering plant in the genus Crocus of the family Iridaceae. It is an autumn-flowering, dwarf, deciduous perennial found in western Europe from southwestern France to Spain. It has been cultivated since Tudor times in Great Britain, where it is now naturalized.
Crocus olivieri is a species of Crocus from Balkans, Albania, Yugoslavia and Bulgaria to Greece and Turkey.
