When to see

June to September


The Yellow horned-poppy is a coastal plant that grows on shingle beaches, cliffs and sand dunes. The golden-yellow flowers appear in June and are followed by the 'horns' - curling seedpods that can be up to 30cm long. When it is broken, the plant exudes a yellow sap which is poisonous.

The Yellow horned-poppy is easily recognised when seen in its beach habitat. It has yellow petals and blue-grey leaves that are fleshy, covered with fine hairs and lobed. It often forms clumps.


Found around the coast of England and Wales, as far north as the Wash on the east coast and the Solway on the west coast.
