Origin & Breeding History: 'PKMP11' originated from a population of Campanula seedlings that resulted from the open hybridization of an unnamed proprietary PKM hybrid breeding line. The breeder conducted this work in Sohus, Denmark in October 2011. The seeds were harvested from the female parent and evaluated. 'PKMP11' was selected in 2012 for its compact and freely branching plant growth habit and dark purple flowers.

Tests & Trials: The detailed description of 'PKMP11' is based on the UPOV report of Technical Examination, application number 2015/2111, purchased from the Community Plant Variety Office in Angers, France. The trial was conducted by the National Institute of Agricultural Botany in Cambridge, United Kingdom in 2016 and 2017. Colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
