Horned Poppy

Botanical Overview

Horned Poppy (Glaucium flavum) belongs to the Papaveraceae family. While not among the most extensively documented medicinal plants, this species has recorded uses that warrant attention from researchers and practitioners. The poppy family (Papaveraceae) includes herbs with milky or colored sap and showy flowers with two or three sepals that fall off as the flower opens. The fruits are capsules with many small seeds. This family produces benzylisoquinoline alkaloids including morphine, codeine, and sanguinarine.

General Description

All parts of the plant, including the seeds, are toxic. It is classed as a noxious weed in some areas of North America, where it is an introduced species. It is grown in gardens as a short-lived perennial but usually grown as a biennial.
