This flower, from which opium is also extracted, sometimes adorns graves in reference to the deep sleep it induces, metaphorically linked to death. Which flower?

The answer

The poppy, associated with the deep sleep it induces in the form of opium, serves as a funerary metaphor for eternal rest. It is distinct from the lily, a symbol of purity, and the chrysanthemum, the traditional flower of mourning in France since the twentieth century.
