}}Crocus biflorus, the silvery crocus,^[1] 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.^[2] It is a cormous perennial growing to {{convert|6|cm|abbr=on}} 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.^[3]

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.^[4] At least 21 subspecies of C. biflorus have been named; furthermore numerous cultivars have been raised for garden use.
