Clematis 'Heirloom'
Listed in the RHS Plant Finder from 1993 to 1996 without description.
In compiling the International Clematis Register and Checklist 2002 the then International Registrar was unable to track down the origins of this cultivar. Private correspondence with a Clematis on the Web contact suggests that it may have been raised in the UK by the late Frank Watkinson.
