Crocus nudiflorus is a species of flowering plant in the genus Crocus of the family Iridaceae. They are dwarf, deciduous perennials found from southwestern France to Spain. It grows from rhizomes, or corms, which spread out into clumps of plants by stolons. Each corm usually sends out one long-tubed, goblet-shaped, or bell-shaped flower. The bloom appears in autumn, or at the end of summer.
They have been cultivated since Tudor times in Britain, where they are now naturalized.
