Origin & Breeding History: 'Whip Bule' originated as part of a planned pedigree breeding program in California, USA. The new variety originated from a cross made by the breeder in February 2002 between the female parent, 'Supertunia Royal Velvet' and the male parent 'PY152', a proprietary line with blue coloured flowers. The resultant seed was sown in June 2002 and in August 2002 a single plant was selected by the breeder based on flower colour, flower form and plant habit.
Tests & Trials: The tests and trials for 'Whip Bule' were conducted in a polyhouse at BioFlora in St. Thomas, Ontario in the spring of 2006. The trials included 15 plants of each variety. Rooted cuttings were transplanted into six inch pots on April 17, 2006. Observations and measurements were taken from 10 plants of each variety. All colour measurements were made using the 2001 Royal Horticultural Society Colour Chart.
