Crocus is a genus of flowering plants in the iris family, known for their vibrant blooms that often appear in early spring. These perennial plants typically grow from corms and can be found in a variety of colors, including purple, yellow, and white. Crocus flowers are often among the first to emerge after winter, signaling the arrival of warmer weather. There are about 80 species of Crocus, many of which are native to Europe and Asia. They thrive in well-drained soil and prefer sunny locations. Crocus is also notable for producing saffron, a valuable spice derived from the stigmas of Crocus sativus, commonly known as the saffron crocus.
