Papaver rhoeas
It has thick, leathery deeply segmented, wavy, bluish-grey leaves, which are coated in a layer of water-retaining wax. The sepal, petals and stamen have a similar structure and form to the red poppy (Papaver rhoeas), except the sepals are not hairy. It grows up to tall, on branched, grey stems. It blooms in summer, between June and October. It has bright yellow or orange flowers, that are across. Later it produces a very long, upright, thin, distinctive horn shaped capsule, which is long. It is divided into two chambers, which split open to reveal the seeds.
