The basal leaves of 'Camp Bulewhit' are larger than those of 'Royal Wave' and have stronger undulation of the margin than those of all the reference varieties. In relation to the flower, the sepals of 'Camp Bulewhit' are clasping while those of 'Royal Wave' and 'Camp Trailbule' are horizontal with incurving tips. The flowers of 'Camp Bulewhit' are larger in diameter with a deeper sinus between the corolla lobes than those of 'Royal Wave'. The inner side of the flowers of 'Camp Bulewhit' is violet blue with white on the inner side of the corolla tube whereas for 'Royal Wave', it is darker violet with darker violet blue margin and light blue violet on the inner side of the corolla tube and for 'Stella Blue' and 'Camp Trailbule', it is darker blue violet fading towards the base of the corolla lobes.

Origin & Breeding History: 'Camp Bulewhit' 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 made in February 2001 between a Campanula isophylla selection with bi-coloured flowers designated 'CL-136-1' as the female parent and another Campanula isophylla selection with white flowers designated 'CL-34-1' as the male parent. The resultant seed was sown in a greenhouse in August 2001. 'Camp Bulewhit' was selected in January 2002 based on its' flower colour, flower form and plant growth habit.

Tests & Trials: Trials for 'Camp Bulewhit' 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' were grown from rooted cuttings and transplanted into 11.5 cm pots on April 30, 2007. The plants of 'Stella Blue' 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.
