Autumn crocus
Colchicum autumnale
Colchicaceae
Naked ladies — a lilac autumn flower without leaves, deadly, and the saffron lookalike this folio exists to name.

Lookalikes
- Saffron — Colchicum in a paella is a poison, not a spice. True saffron is Crocus sativus; autumn crocus is a lily in disguise.
Lore
Colchis, Medea’s country, named it. The Greeks already knew it as a poison. Modern gout clinics use colchicine in micrograms; the corm contains a lottery. Medieval ‘hermodactyl’ was this plant in the pharmacy. The saffron confusion is newer and worse, because it happens in a kitchen.
The Herbarium — a teaching catalog, not a clinic. Traditional use is history, not a prescription. USDA 6b dates are a week either way, not a promise. Do not eat, drink, or harvest a plant you cannot name.
