Yellow Horned Poppy, or also known as a Yellow Hornpoppy (Glaucium flavum) is part of the Papaveraceae family, and is a summer flowering plant. The Yellow Horned Poppy is never found in land and is only found along the seashore, although it is sometimes classed as a weed rather than a flower.
The down side of this plant is that all parts of the plant, including the seeds, are toxic and in the worst case, can result in respiratory failure (FDA poisonous plants database).
The leaves of this plant have a leather like texture and are coated in a layer of water retaining wax. Although its structure is similar to that of the common red poppy, the stem is not hairy and the seeds are held in a distinctive horn shaped pod which is between 15 – 30cm in length which is split into two seperate chambers.
Height: 15 – 30cm
Flowering Time: June to September
Preferred Conditions: Prefers to grow on shingle and stony grounds and in places such as beaches and cliffs.
