Origin & Breeding History: 'Tor Bule' originated from a hybrid cross conducted in July 2004 in Andijk, The Netherlands. The female parent was a proprietary seedling with blue flowers and the male parent was a proprietary seedling with blue and white flowers. The resultant seed was sown in a greenhouse in December 2004. In March 2005, a single plant was selected from the progeny based on flower colour and plant habit.

Tests & Trials: Trials for 'Tor Bule' were conducted in a poly-house during the spring of 2009 at BioFlora Inc. in St. Thomas, Ontario. The trial included a total of fifteen plants per variety. All plants were grown from rooted cuttings and transplanted into 11 cm pots on May 7, 2009. Observations and measurements were taken from ten plants or parts of plants on June 9, 2009. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
