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 Greece, former Yugoslavia, Bulgaria, 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.

The Latin specific epithet flavus means "yellow". [5]

Description

Crocus flavus is a herbaceous perennial geophyte growing from a corm. The globe shaped corms are relatively large for a crocus species, and the tunics have parallel fibers. [6] The chromosome count is 2N=8 with 11 B-chromosomes. [7]

Subspecies [1]
  1. Crocus flavus subsp. dissectusT.Baytop & B.Mathew - western Turkey
  2. Crocus flavus subsp. flavus - Greece, Turkey, Balkans; naturalized in Utah
  3. Crocus flavus subsp. sarichinarensisRukšans - 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]
