M. betonicifolia
This is Meconopsis betonicifolia in my garden in east Fife. It is a rather wishy washy mauve. The temperature, the season and the location can alter the colour of Meconopsis from year to year and this site on the east of Scotland tends to produce rather washed out mauves. The one big blue poppy I have never seen anything but the most perfect blue is Slieve Donard ( a x. Sheldonii type). Fortunately this is still widely available, divides up readily and strong growing.
