Meconopsis delavayi. This is a really beautiful perennial species. It is not easy but is safely in cultivation and seed is occasionally offered in seed exchanges. I grow this in a small bed which gets little direct sun light. Both these images have been given to me. The top is a garden plant and the bottom an image from the wild. It is deciduous but has deep strong tap roots and these have been used successfully to produce new plants from root cuttings. In theory this plant comes from limestone areas but I do not think soil pH either side of  neutral is significant.
