Origin & Breeding History: 'PKM06' originated from a population of Campanula seedlings that resulted from the hybridization between two proprietary PKM hybrid breeding lines. The planned breeding program aimed at creating new Campanula varieties with greater floriferousness, more colourful flowers and a compact plant growth habit. The cross was made in April 2014 by a breeder in Søhus, Denmark. The resulting seeds were harvested from the female parent and the resulting progeny were evaluated. The new variety was selected based on plant growth habit and flower colour. In June 2016, the final selection of 'PKM06' was made based on its compact growth habit and double light blue coloured flowers.
Tests & Trials: The detailed description of 'PKM06' is based on the UPOV report of Technical Examination, application number 2016/1610, 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 2017. Colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
