Crocus sativus, commonly known as saffron crocus, or autumn crocus,
 is a
flowering plant of the
genus in the Iridaceae
family. It is best known for producing the spice
saffron from the filaments that grow inside the flower. The term "autumn crocus" is also mistakenly used for flowers in the Colchicum species. However, crocuses have 3 stamens and 1 style, while colchicum have 6 stamens and 3 styles and are toxic.
perennial plant species is unknown in the wild.
 Human cultivation of saffron crocus and
use of saffron have taken place for more than 3,500 years and spans different cultures, continents, and civilizations, see
history of saffron. Crocus sativus is currently known to grow in the
East Asia, and
Saffron may be the triploid form of a species found in Eastern Greece,
Crocus cartwrightianus; it probably appeared first in Crete. An origin in Western or Central Asia, although often suspected, is not supported by botanical research.
