Species of flowering plant
From Wikipedia, the free encyclopedia
Crocus flavus, known as yellow crocus,[3] Dutch yellow crocus or snow crocus,[4] 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,[1] 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.

- Crocus flavus subsp. dissectus T.Baytop & B.Mathew - western Turkey
- Crocus flavus subsp. flavus - Bulgaria, Greece, Kosovo, North Macedonia, Romania, Serbia, Turkey; naturalized in Utah
- Crocus flavus subsp. sarichinarensis Rukšans - Turkey
Crocus flavus subsp. flavus has gained the Royal Horticultural Society's Award of Garden Merit.[8]
Cultivation
Crocus flavus naturalizes well in gardens, and has escaped cultivation and become naturalized in the US state of Arkansas.[9] The majority of plants grown in gardens are triploids that do not produce seeds and are propagated vegetatively.[6] The species has been hybridized with other crocus species to produce a number of other cultivars.[4]
Cultivars include Crocus flavus 'Grosser Gelber' ('Big Yellow'), with large orange-yellow flowers.[6]
