Glebionis segetum (syn. Chrysanthemum segetum) is a species of the genus Glebionis, 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.[2][3][4] Common names include corn marigold and corn daisy.

Glebionis segetum is a herbaceous perennial plant growing to 80 cm tall, with spirally arranged, deeply lobed leaves 5–20 cm long. The flowers are bright yellow, produced in capitulae (flowerheads) 3.5-5.5 cm in diameter, with a ring of ray florets and a centre of disc florets.[5]

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.

Glebionis segetum was formerly treated in the genus Chrysanthemum, but under a 1999 decision of the International Botanical Congress, that genus has been redefined with a different circumscription to include the economically important florist's chrysanthemum (now Chrysanthemum indicum).

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.[6]

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.[7]
