Crocus

Crocus (plural: crocuses, croci) is a genus in the iris family comprising about 80 species of perennials growing from corms. Many are cultivated for their flowers appearing in autumn, winter, or spring. Crocuses are native to woodland, scrub and meadows from sea level to alpine tundra in central and southern Europe, North Africa and the Middle East, on the islands of the Aegean, and across Central Asia to western China.

There are about eighty species of crocus (of which approximately 30 are cultivated). Their cup-shaped, solitary, salverform flowers taper off into a narrow tube. Their color varies enormously, although lilac, mauve, yellow and white are predominant. The grass-like, ensiform leaf shows generally a white central stripe along the leaf axis. The leaf margin is entire. Crocuses typically have three stamens. The spice saffron is obtained from the stigmas of Crocus sativus, an autumn/fall-blooming species.
