Origin & Breeding History: 'Balsunbur' originated from a cross pollination conducted in October 2004 in Arroyo Grande, California, United States, as part of a controlled breeding program. The cross was between the female parent, the proprietary breeding selection designated '2840-1' and the male parent 'Jam Burg'. The initial selection of 'Balsunbur' was made in July 2005 based on growth habit, branching habit, flower size and flower shape. The variety has been maintained since that time through the use of vegetative cuttings.

Tests & Trials: Trials for 'Balsunbur' 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 May 26, 2010. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
