Awards: AM (1968)
Named by: Major Knox-Finlay, 1968. Registered by: The Meconopsis Group, 2017.
A cultivar of the Nepal form of M. grandis, now M. grandis subsp. grandis, which had dark purple flowers that were said to be anything but crimson! It was once misnamed as M. grandis Prains' form, but was renamed and exhibited by the Knox-Finlays as M. grandis 'Keillour Crimson'. No plants of this cultivar are now known to us under this name.
