Colchicum autumnale, commonly known as autumn crocus or meadow saffron, is a perennial wildflower native to Europe. It is distinguished by its pale lilac to pink flowers that bloom in autumn without leaves, a trait that sets it apart from most flowering plants. The leaves appear later in spring, giving rise to the old saying “naked ladies” in some regions. Despite its crocus-like appearance, it is unrelated to true crocuses. Historically, Colchicum autumnale has been both valued and feared: it contains colchicine, a powerful toxin long used in medicine but dangerous if misused, making it one of Europe’s most striking and poisonous meadow plants.
