There are quite a number of named species under the basic title of Meconopsis horridula. These range from a beautiful strong medium blue like this through a whole range of muddy purple to white. They have been split into separate species.M. horridula is a high altitude species and very difficult. This M. racemosa in a nice strong colour. Usually biennial and easy from seed and will grow in hot dry places in poor soil. It is very spiny and harvesting seed from very prickly dry pods needs care! Meconopsis rudis is much the same and putting these spiny blue plants into the right species is not easy. Grow from which ever seed is offered to you and then select seeds for yourself and to share with others from the best colour and growth of forms.
