ശരത്കാല ക്രോക്കസ്

Some species, known as "autumn crocus", flower in late summer and autumn, often before their leaves appear. They should not be confused with a different genus of autumn-flowering plants, Colchicum. Autumn-flowering species of crocus include:

  • C. banaticus (syn. C. iridiflorus)
  • C. cancellatus
  • C. goulimyi
  • C. hadriaticus
  • C. kotschyanus (syn. C. zonatus)
  • C. laevigatus
  • C. ligusticus (syn. C. medius )
  • C. niveus
  • C. nudiflorus
  • C. ochroleucus
  • C. pulchellus
  • C. sativus (saffron crocus)
  • C. serotinus
  • C. speciosus
  • C. tournefortii

C. laevigatus has a long flowering period which starts in late autumn or early winter and may continue into February.
