Origin & Breeding History: 'Balsundarco' originated from a cross conducted during February, 2004, at Arroyo Grande, California, as part of a controlled breeding program. The female parent was the proprietary petunia breeding selection designated 1694-1, characterized by its scarlet red flower colour, dark green leaf and trailing growth habit. The male parent of 'Balsundarco' was the proprietary petunia breeding selection designated SA2091-1, characterized by its medium coral flower colour, medium green leaf and trailing growth habit. The initial selection was made on October 26, 2004. Asexual propagation since that time has been through the use of vegetative cuttings. 'Balsundarco' was selected for its mounded, trailing, growth habit.

Tests & Trials: The trials for 'Balsundarco' were conducted during the spring of 2007, in a polyhouse in St. Thomas, Ontario. The trials consisted of a total of 15 plants of the candidate and reference varieties. All plants were grown from rooted cuttings planted into 15cm pots on April 24, 2007. Observations and measurements were taken from 10 plants of each variety on June 5, 2007. All colour measurements were made using the 2001 Royal Horticultural Society (RHS) Colour chart.
