''Crocus biflorus'' is a species of flowering plant in the genus ''Crocus'' of the family Iridaceae, native to southeastern Europe and southwestern Asia, including Italy, the Balkans, Ukraine, Turkey, Caucasus, Iraq, and Iran.〔(Kew World Checklist of Selected Plant Families )〕 It is a cormous perennial growing to tall and wide. It is a highly variable species, with flowers in shades of pale mauve or white, often with darker stripes on the outer tepals. The flowers appear early in spring. ==Classification== According to the taxonomic classification proposed by Brian Mathew in 1982, ''C. biflorus'' falls within the series ''Biflori'' of the section ''Nudiscapus'' within the genus ''Crocus''. However, modern DNA analysis is challenging whether the series ''Biflori'' can be separated from the ''Reticulati'' and ''Speciosi'' series.〔Brian Mathew, Gitte Petersen & Ole Seberg, A reassessment of ''Crocus'' based on molecular analysis, ''The Plantsman'' (N.S.) Vol 8, Part 1, pp50–57, March 2009〕 At least 21 subspecies of ''C. biflorus'' have been named; furthermore numerous cultivars have been raised for garden use. ;Subspecies〔 # ''Crocus biflorus'' subsp.
