Origin & Breeding History: 'Balsunwhite' originated from a cross conducted during November 2003, at Arroyo Grande, California, as part of a controlled breeding program. The female parent was the Petunia variety 'Easy Wave White', characterized by its' white flower, dark green leaf and prostrate, trailing growth habit. The male parent is the proprietary Petunia breeding selection designated '2111-1', characterized by its' creamy white flower, dark green leaf and semi-upright growth habit. The initial selection was made on September 20, 2004. Asexual propagation since that time has been through the use of vegetative cuttings. 'Balsunwhite' was selected for its pure white flowers, very dark green foliage and vigorously trailing growth habit.

Tests & Trials: The trials for 'Balsunwhite' were conducted during the summer of 2007, in a polyhouse in St. Thomas, Ontario. The trials consisted of 15 plants per variety. All plants were grown from rooted cuttings planted into 11.5 cm pots on July 10, 2007. Observations and measurements were taken on August 21, 2007 from 10 plants of each variety except for plant height and plant width where 5 plants of each variety were used. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour chart.
