Meconopsis

(via)

From The Meconopsis Group:

The genus comprises a race of mountain plants, a few species growing at the highest altitudes of any flowering plants in the world...others occur at lower, but nonetheless montane, altitudes. However, although they are distributed along the Himalayan range, many species also occur in the mountains of western China and the high plateaux of Tibet. There are 45-50 known species and they are all...native to these Asian regions. Arguably the most popular of the Meconopsis grown in gardens have blue flowers, but other colours are well represented, e.g. the striking red of M. punicea and a number of species such as M. pseudointegrifolia are yellow.
