Chrysanthemum segetum) is a species of flowering plant in the family Asteraceae, probably native only to the eastern Mediterranean region but now naturalized in western and northern Europe as well as China and parts of North America.

[6][7] Glebionis segetum is widely naturalised outside of its native range, colonising western and central Europe with early human agriculture; it can be an invasive weed in some areas.

The corn marigold appears to have been a serious weed during the 13th century in Scotland, as suggested by a law of Alexander II which states that if a farmer allows so much as a single plant to produce seed in amongst his crops, then he will be fined a sheep.

[9] In Crete and Greece, the leaves and the tender shoots of a variety called neromantilida (νερομαντηλίδα) are eaten raw in salads or browned in hot olive oil by the locals.

The epithet segetum is a plural noun in the genitive case, meaning "of the corn[fields]",[11] so does not change its ending to agree with the feminine genus name.
