Origin & Breeding History: 'Sunphlocoro' originates from crossing the breeding line '2Ph-38a' as the female parent and the breeding line '2Ph-38b' as the pollen parent. This cross was conducted at Higashiomi-shi, Shiga-ken, Japan, in June 2002. From December 2002, the seedlings were sown and grown in pots on trial in a greenhouse. In May 2003, one seedling was selected in view of shape and flower colour. The seedling was propagated by cuttings and trialed to examine the botanical characteristics of that plant at the Omi R&D Center of Suntory Flowers Ltd.

Tests & Trials: PBR trials were conducted in a polyhouse during the spring of 2007 in St. Thomas, Ontario. Trials included 15 plants of the candidate and reference variety. Rooted cuttings were transplanted into 15cm pots on May 1, 2007. Observations and measurements were taken from 10 plants of each variety on June 27, 2007. All colour measurements were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
