About

Crocus vernus (spring crocus, giant crocus) is a species of flowering plant in the 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 inches (10–15 cm).

Where it grows

Within Britain, it can be found in grasslands, including churchyards and roadside verges.
