Origin & Breeding History: The variety 'Balcabdebu' originated from a cross pollination conducted in Elburn, Illinois, USA in August 2006. The female parent was a proprietary breeding selection designated as 2191-3-1, characterized by its veined dark blue coloured flowers, medium green foliage and moderately vigorous trailing growth habit. The male parent was a proprietary breeding selection designated as 2172-1-1-13, characterized by its dark blue coloured flowers, medium green foliage and moderately vigourous trailing growth habit. The initial selection was made in June 2007. The variety was selected for its flower colour and well branched mounded growth habit. Asexual propagation since that time has been through the use of vegetative cuttings.

Tests & Trials: Trials for 'Balcabdebu' were conducted in a polyhouse during the summer of 2011 in St. Thomas, Ontario. The trial included a total of 20 plants each of the candidate and reference varieties. All plants were grown from rooted cuttings and transplanted into 30 cm hanging baskets on May 12, 2011. Each basket contained 4 cuttings with a total of 5 baskets per variety. Observations and measurements were taken from 10 plants of each variety on July 4, 2011. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
