About

Crocus flavus, known as yellow crocus, Dutch yellow crocus or snow crocus, is a species of flowering plant in the genus Crocus of the family Iridaceae. It grows wild on the slopes of Bulgaria, Greece, parts of former Yugoslavia (North Macedonia, Kosovo and Serbia), Romania and northwestern Turkey, with fragrant bright orange-yellow flowers. It is a small crocus (5–6 cm (2–2 in), despite the names of some cultivars, compared to the giant Dutch crocuses (C. vernus). Its cultivars are used as ornamental plants.

The Latin specific epithet flavus means "yellow".

How to grow it

Crocus flavus naturalizes well in gardens, and has escaped cultivation and become naturalized in the US state of Arkansas. The majority of plants grown in gardens are triploids that do not produce seeds and are propagated vegetatively. The species has been hybridized with other crocus species to produce a number of other cultivars.

Cultivars include Crocus flavus 'Grosser Gelber' ('Big Yellow'), with large orange-yellow flowers.
