Origin & Breeding History: 'Camp Trailbule' was developed as part of a planned pedigree breeding program by the breeder, Pim Kaagman, of Goldsmith Seeds Europe B.V., in Andijk, The Netherlands. It originated from a cross between a Campanula isophylla line designated 'CD-20-1' as the female parent and an unnamed Campanula fragilis plant as the male parent. The resultant seed was sown in a greenhouse in August 1999. 'Camp Trailbule' was selected in January 2000 based on its' flower colour, flower form and plant growth habit.

Tests & Trials: Trials for 'Camp Trailbule' were conducted in a poly-house during the summer of 2007 at BioFlora Inc. in St. Thomas, Ontario. The trial included a total of fifteen (15) plants per variety. All plants with the exception of 'Stella Blue' and 'Blue Uniform' were grown from rooted cuttings and transplanted into 11.5 cm pots on April 30, 2007. The plants of 'Stella Blue' and 'Blue Uniform' were grown from seed. Observations and measurements were taken from ten (10) plants or parts of plants from July 6 to 9, 2007. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
