The Welsh poppy is a perennial flowering plant in the poppy family "Papaveraceae". It has yellow to orange flowers and is widely grown as a garden plant. It is a native of damp, rocky sites in upland areas of Western Europe from the British Isles to the Iberian Peninsula. The plant has pinnately divided leaves composed of pinnately divided leaflets. It can grow between 30–60 cm (12–24 in) tall. It blooms between June and July and spreads easily from the numerous small black seeds produced in the summer, from a long, ribbed capsule that opens with flaps.
