This plant, or one that resembles it, is dangerous. Identifying is not authorising: no app has the authority to tell you that you may eat or touch a plant.


The lilac flower that rises out of the ground in autumn with not a single leaf around it, as if someone had stuck it there. It is one of Europe's deadliest plants and has no antidote.

How to tell it
In autumn: a solitary pink-lilac flower with no leaves. In spring: a tuft of broad glossy leaves with no smell at all, and that is when it is dangerous, because it looks like a wild garlic or a lily.
What it is confused with
Wild leek
Allium ampeloprasum
This confusion has killed people across Europe. The rule is smell: garlic smells of garlic. Autumn crocus smells of nothing. If it does not smell, do not pick it.

None. The colchicine it contains is used as an exact-dose, controlled-manufacture medicine; in the plant, the margin between effect and death is extremely narrow. It is also toxic to livestock and passes into milk.
