Yellow Horned Poppy (Glaucium flavum) is a member of the Papaveraceae family, native to western Europe. Glaucium flavum contains glaucine, an alkaloid similar in effect to codeine, in that it has cough suppressant activity but without being addictive.

Glaucine is an alkaloid found in several different plant species such as Glaucium flavum, Glaucium oxylobum, Croton lechleri and Corydalis yanhusuo. It has bronchodilator and anti inflammatory effects, acting as a PDE4 inhibitor and calcium channel blocker, and is used medically as an antitussive in some countries. Glaucine may produce side effects such as sedation, fatigue, and a hallucinogenic effect characterised by colourful visual images, and has recently been detected as a novel recreational drug (Info on Glaucine).

Care and Cultivation of Glaucium flavum

Glaucium flavum seed can be sown just under the surface in spring, summer or autumn, direct sow into garden or in pots and separate once seedlings begin to crowd each other. Germination in 1-3 weeks, full sun to part shade. Biennial or perennial herb to 30cm tall.

Quite attractive to native bees as a pollen source, ours were covered in them each morning!
