Origin & Breeding History: 'Sunsurfgigabu' originated from a controlled cross between 'Titan Blue' as the female parent and '79-200' as the male parent. The cross was made in August 2001 at Yokaichi-shi, Shiga-ken, Japan. In April 2002, 80 seedlings were obtained from the cross and grown in pots in the glasshouse for evaluation. In August 2002, one seedling was selected based on its growth habit, flower size and colour. That seedling was propagated by cuttings and a trial was carried out by flower potting and bedding from April to September 2003.

Tests & Trials: The tests and trials for 'Sunsurfgigabu' were conducted in a polyhouse at BioFlora in St. Thomas, Ontario in the spring of 2006. The trials included 15 plants of each variety. Rooted cuttings were transplanted into six inch pots on April 17, 2006. Observations and measurements were taken from 10 plants of each variety. All colour measurements were made using the 2001 Royal Horticultural Society Colour Chart.
