Ecological Considerations:
Glaucium flavum, commonly known as Horn Poppy is an herbaceous plant, usually biennial, that is only found on the seashore, never inland. It grows well on shingle beaches and cliffs and dunes reaching heights of one to three feet tall. The bright yellow flowers of the Horn Poppy are about three inches across. The flowers bloom between June and October. After the flowers appear they are followed by the ‘horns’ – curling seedpods that can grow up to a foot long. The seed pod is divided into two chambers, which split open to reveal the seeds. The Horn Poppy fruit is dry and splits open when it is ripe.
The plant has thick fleshy blue-grey leathery leaves that are segmented and are covered with fine hairs, are lobed, and are coated in a layer of water-retaining wax.
