Origin & Breeding History: 'PKM01' originated from a breeding program with the objective of developing new Campanula varieties with compact growth habit, greater floriferousness and more colourful flowers. An open hybridization was conducted by the breeder in Sohus, Denmark in July 2007 and involved approximately 50 different species of Campanula within an insect proof screen house that contained bumble bees. 'PKM01' was selected in September 2008.

Tests & Trials: The detailed description of 'PKM01' is based on the UPOV report of Technical Examination, application number 2012/1350, purchased from the Community Plant Variety Office in Angers, France. The trials were conducted by the National Institute of Agricultural Botany in Cambridge, United Kingdom in 2013. Colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
