26-9-2023 REVILLA, ARAGON - FALSE MEADOW SAFFRON (Colchicum montanum)

 Colchicum autumnale, commonly known as autumn crocus, meadow saffron, naked boys or naked ladies, is a toxic autumn-blooming flowering plant that resembles the true crocuses, but is a member of the plant family Colchicaceae, unlike the true crocuses, which belong to the family Iridaceae. It is called "naked boys/ladies" because the flowers emerge from the ground long before the leaves appear. Despite the vernacular name of "meadow saffron", this plant is not the source of saffron, which is obtained from the saffron crocus, Crocus sativus – and that plant, too, is sometimes called "autumn crocus".

The species is cultivated as an ornamental in temperate areas, in spite of its toxicity. The cultivar 'Nancy Lindsay' has gained the Royal Horticultural Society’s Award of Garden Merit.

Colchicum plants are deadly poisonous due to their colchicine content and have been mistaken by foragers for Allium ursinum (ramsons or wild garlic), which they vaguely resemble.

This plant (and colchicine itself) poses a particular threat to felines. The corms of meadow saffron contain the highest level of toxins, but all parts of the plant are regarded as poisonous.
