The yellow horned-poppy (Glaucium flavum)
is a native of Europe and western Asia but is a familiar wild flower on shingle
beaches all round the coast of Great Britain except for northern Scotland. This
suggests that the plant might have reached these shores courtesy of a shipwreck
centuries ago and spread along the coast. Despite its preference for shingle
beds above the high-water mark, it will also grow on sand and cliff tops.
The yellow horned-poppy will grow up to 36
inches (90 centimetres) high, but many specimens are much more low-lying than
that due to being constantly battered by winds off the sea. The lower leaves
grow on stalks off the main stem and have hairy lobes, whereas the upper leaves
clasp the stem and have less prominent lobes.
The bright yellow flowers are up to three
inches (7.5 centimetres) across and are seen from June to October. They are
succeeded by seed capsules that are long and thin, up to 12 inches (30
centimetres) in length, and these form the “horns” that give the plant its
name.
The yellow horned-poppy has an
orange-coloured, foul-smelling sap that is highly poisonous, as are all parts
of the plant. This is a wild flower that should be admired from a safe distance
rather than be handled.
