Origin & Breeding History: 'Camp Whit' 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 selection designated 'CW-128-1' as the female parent and another Campanula isophylla selection designated 'CR-2-1' as the male parent made in February 2000. The resultant seed was sown in a greenhouse in August 2000 and a single plant, 'Camp Whit', was selected in January 2002 based on its' early flowering time, quantity of flowers and plant growth habit.

Tests & Trials: Trials for 'Camp Whit' 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. The plants of 'Camp Whit' were grown from rooted cuttings and transplanted into 11.5 cm pots on April 30, 2007. The plants of 'Stella White' and 'Uniform White' were grown from seed. Observations and measurements were taken from ten (10) plants or parts of plants from July 28 to August 1, 2007. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
