Origin & Breeding History: 'Balperblues' originated from a cross pollination conducted in the summer of 2005 at Sudlohn, Germany, as part of a controlled breeding program. The cross was between the female parent designated '05P633' and the male parent designated '05P413, both proprietary Petunia breeding selections. The initial selection of 'Balperblues' was made in May 2006 based on flower colour, flower size, branching habit and branch size. The variety has been maintained since that time through the use of vegetative cuttings.

Tests & Trials: Trials for 'Balperblues' were conducted in a polyhouse during the spring of 2010 in St. Thomas, Ontario. The trial included a total of 15 plants each of the candidate and reference varieties. All plants were grown from rooted cuttings and transplanted into 15 cm pots on April 27, 2010. Observations and measurements were taken from 10 plants of each variety on June 1, 2010. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
