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 threestamens. The spice saffron is obtained from the stigmas of Crocus sativus, an autumn/fall-blooming species.
