Glaucium flavum (yellow hornpoppy or yellow horned poppy) is a summer flowering plant in the Papaveraceae family, which is native to Northern Africa, Macronesia, temperate zones in Western Asia and the Caucasus, as well as Europe. Habitat: the plant grows on the seashore and is never found inland. All parts of the plant, including the seeds, are toxic and can produce a range of symptoms up to and including respiratory failure resulting in death FDA poisonous plants database.[1] It is a noxious weed in some areas of North America, where it is an introduced species. The thick, leathery deeply segmented, wavy, bluish-grey leaves are coated in a layer of water retaining wax. The sepal, petals and stamen have a similar structure and form to the Red Poppy (Papaver rhoeas) except the sepals are not hairy. Prolific quantities of seeds are held in a distinctive horn shaped fruit some 15 to 30 cm in length, which is divided into two chambers.[2]

In poetry[edit]

A poppy grows upon the shore,

Bursts her twin cups in summer late:

Her leaves are glaucus-green and hoar,

Her petals yellow, delicate.

She has no lovers like the red,

That dances with the noble corn:

Her blossoms on the waves are shed,

Where she stands shivering and forlorn.
Shorter Poems Robert Bridges


Glaucine is the main alkaloid component in Glaucium flavum.[3] Glaucine has bronchodilator and antiinflammatory effects, acting as a PDE4 inhibitor and calcium channel blocker,[4] and is used medically as an antitussive in some countries.[5] Glaucine may produce side effects such as sedation, fatigue, and a hallucinogenic effect characterised by colourful visual images,[6][7] and has recently been detected as a recreational drug.[8] For a detailed bibliography on Glaucine and Glaucium flavum see: National Agricultural Library (Glaucium flavum entry)
