Common Crocus

<em>Crocus vernus</em>, commonly known as the common crocus or spring crocus, is a small bulbous perennial plant in the family Iridaceae. Native to Europe, it has been widely cultivated and naturalized across North America. Common crocus typically grows in alpine meadows, subalpine grasslands, and woodland edges, often emerging through snow in early spring, making it one of the earliest flowering plants of the season. The flowers are solitary and cup-shaped, appearing before the leaves, and range in color from white and lilac to deep purple. The species has long been cultivated as an ornamental plant and is one of the parents of many garden crocus cultivars. Its corms are eaten by rodents and its flowers provide an early-season nectar source for bees and other pollinators. Biological traits of this species remain poorly documented in the scientific literature.
