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.
Division in spring.
Seed - sown in September - November.
Seed has very short viability and should be stored refrigerated until it is sown.
Seed needs light to germinate so it should not be covered or only covered with a very thin layer of soil or sand. Stored at 20°C (68°F) for two weeks and then stored outside until germination.
Not drought tolerant during summer. Grows best in slightly acidic, fertile soil.
