Origin & Breeding History: 'Sunsurfpapu' originated from a controlled cross between 'Ultra Red' as the female parent and an unnamed breeding line as the male parent. The cross was made in August 1998 at Yokaichi-shi, Shiga-ken, Japan. In April 1999, 100 seedlings were obtained from the cross and grown in pots in the glasshouse for evaluation. In July 1999, 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 2000.

Tests & Trials: The tests and trials for 'Sunsurfpapu' 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.
