Meconopsis is a genus of flowering plants in the family Papaveraceae. The species have attractive flowers and have two distinct ranges. A single species, Meconopsis cambrica, also known as the Welsh poppy, is indigenous to England, Wales, Ireland, and the fringes of Western Europe. The other 40 or so (depending on classification) species are found in the Himalayas. Within the Himalayan types there is much debate as to what constitutes a particular species as many readily hybridise with each other and produce viable seed. It is likely that some individually-named species are in fact a single species but with an under-appreciated morphological diversity.
A large proportion of species are monocarpic and as such are notoriously difficult to maintain in cultivation.
