Origin & Breeding History: 'PKMP05' originated from a planned breeding program aimed at creating new Campanula cultivars with improved form/habit and floral traits. A cross was made during 2003 in Odense, Denmark between 'PKMP01' as the female parent and '08.98.05' as the male parent. The new cultivar was selected based on plant habit and ability to flower more freely, and named '08.02.06'.

Tests & Trials: Trials were conducted during the summer of 2006 in Oxford Station, Ontario. Trials consisted of 10 plants of each variety individually grown in 12.5cm pots in a polyhouse. Plants were spaced 15cm apart.
