Meconopsis x beamishii. This ia a hybrid between a form of M. grandis and either M. integrifolia or M. pseudointegrifolia. The blue/ yellow crosses always seem to be this same creamy white. It will hopefully be perennial but only a proportion are. The cross with the yellow species and M. betonicifolia is M. x sarsonsii. The leaves of the hybrids usually more closely resemble the blue parent and this is how the two can be told apart.
