Did you know

  • Despite the common name 'autumn crocus', Colchicum is not a true crocus at all — it's a member of an entirely different plant family.
  • The flowers emerge in fall on bare leafless stems, then leaves appear the following spring and die back by summer — a strange backwards life cycle.
  • Colchicum is the source of colchicine, a powerful drug used to treat gout and familial Mediterranean fever — and also used by plant breeders to artificially double chromosomes and create polyploid hybrids.
  • Every part of the plant is extremely toxic, and there's no antidote for colchicine poisoning — historically it was used as a discreet murder weapon.
  • Vincent van Gogh painted Colchicum in his garden at Saint-Rémy, capturing the strange beauty of pink flowers springing up from autumn earth.
