Cultivation
''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.
