Crocus vernus (spring crocus, giant crocus) is a species in Family Iridaceae, native to the Alps, the Pyrenees, and the Balkans. Its cultivars and those of Crocus flavus (Dutch crocus) are used as ornamental plants. The Dutch crocuses are larger than the other cultivated crocus species (e.g., Crocus chrysanthus). Depending on the year, Crocus vernus starts flowering about the same time or up to 2 weeks after Crocus chrysanthus (snow crocus) starts flowering. Height: 4–6" (10–15 cm).

Taxonomy
