Meconopsis grandis There are 3 sub species defined for this genus and they are discussed on the main website. The above images were taken in Caithness where all the blue poppies grow exceptionally well and multiply and can be divided. This image does have a tall plant of M. grandis KEKE BUT the rest are the tetraploid hybrid Lingholm. This is easily obtained with masses in the seed exchanges and sometimes available commercially. It is tolerant of heat and dry and if you want a big blue poppy this is the one to try first. M. grandis forms are also available from seed exchanges and not particularly difficult in good rich growing conditions, for choice, in partial shade
