Saffron crocus vs Meadow saffron
Both flower in autumn straight from bare ground, both are lilac, and both are called autumn crocus, which makes this the most dangerous mix-up in the garden. Saffron crocus (Crocus sativus) is a true crocus, with three stamens and the three long red threads that are the spice. Meadow saffron (Colchicum autumnale) belongs to a different family, has six stamens and bigger goblets, and every part of it is extremely poisonous, sometimes fatal. Never pick saffron from a plant you cannot name for certain.
