Origin & Breeding History: 'Sunsurfpinkai' is the result of the cross made in August 2003 between the female parent 'Madness Rose Star' and the male parent 'P55h5' conducted at Higashiomi-shi, Shiga-ken, Japan. In April 2004, 60 seedlings were obtained from that cross and grown in pots in the glasshouse and evaluated. In September 2004, one seedling was selected in view of its growth habit, flower size and colour. The selected plant was propagated by cuttings and grown in pots and trialed in April-September 2005.

Tests & Trials: Tests and trials were conducted in a poly house in the spring of 2008 in St. Thomas, Ontario. There were 15 plants of each variety individually grown in 15 cm plastic pots. All colour measurements were made using the 2001 Royal Horticultural Society Colour Chart.
