Origin & Breeding History: The variety 'Balvijac' originated from a cross pollination conducted in November 2003 at Guadalupe, California, USA. The female parent was a proprietary breeding selection designated 5573, characterized by its white flower colour with a black coloured blotch, medium green foliage colour and trailing growth habit. The male parent was a proprietary breeding selection designated 5750-3, characterized by its dark blue flower colour with a black blotch, medium green foliage colour and trailing growth habit. The initial selection was made in November 2005 and propagation since that time has been through the use of vegetative cuttings. Selection criteria included unique flower colour pattern, vigour and growth habit.

Tests & Trials: Trials for 'Balvijac' were conducted in a polyhouse during the spring of 2010 in St. Thomas, Ontario. The trial included a total of fifteen plants of the candidate and reference varieties. The candidate variety was grown from rooted cuttings while the reference varieties were grown from seed. All plugs were transplanted into 11 cm pots on May 11, 2010. Observations and measurements were taken from ten plants or parts of plants on June 7, 2010. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
