A picture I may have already used but it makes a point that may help people new to this amazing genus of plants. Nearly every keen grower of Meconopsis that I know calls this plant M. napaulensis. They can be pink, white or red and many plants with this name can be large and yellow as well! Relatively recently Chris Grey-Wilson decided that M. napaulensis was a small yellow monocarpic (dies after flowering) evergreen plant with a restricted distribution in Nepal. I have taken to putting the name in inverted commas implying it is a common usage name and not a technical taxonomic name. Most seed exchange offer this as M. napaulensis rather than the true wild yellow species.
