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. The saffron crocus was 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.
Colchicum autumnale, commonly known as autumn crocus, meadow saffron, naked boys or naked ladies, is a toxic autumn-blooming flowering plant that resembles the true crocuses, but is a member of the plant family Colchicaceae, unlike the true crocuses, which belong to the family Iridaceae. It is called "naked boys/ladies" because the flowers emerge from the ground long before the leaves appear. Despite the vernacular name of "meadow saffron", this plant is not the source of saffron, which is obtained from the saffron crocus, Crocus sativus – and that plant, too, is sometimes called "autumn crocus".

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: Greece, especially in the island of Crete, Bulgaria, Albania and North Macedonia. There are four subtypes: sieberi (Crete), atticus, nivalis and sublimis.

Tecophilaea cyanocrocus, the Chilean blue crocus, is a flowering perennial plant that is native to Chile, growing at 2,000 to 3,000 m elevation on dry, stony slopes in the Andes mountains. Although it had survived in cultivation due to its use as a greenhouse and landscape plant, it was believed to be extinct in the wild due to overcollecting, overgrazing, and general destruction of habitat, until it was rediscovered in 2001.
