Meconopsis, is a genus of around 40 species in the poppy family, Papaveraceae. All except one are native to the Himalayas. The Welsh poppy is native to Britain and it's placement in this genus is debated. The Himalayan species grow at high altitudes in moist meadows along with Himalayan primroses. These species are compatible in gardens as they thrive in moist, fertile soil and part shade.
