Origin & Breeding History: 'Sunrenirirepa' was discovered in January of 1997 as a mutation of the variety 'Sunrenimu' in production at the Omi Research & Development Center, Flower Division of Suntory Ltd., located at 863-1, Aza-Iketani, Omori-cho, Yokaichi-shi, Shiga-ken, Japan. It was selected based on flower colour and further evaluated in potting and bedding trials beginning in April of 1997.

Tests & Trials: The test and trial for 'Sunrenirirepa' was conducted in a polyhouse during the summer of 2004 in St. Thomas, Ontario. The trial included a total of 15 plants of each variety. All plants were grown from rooted cuttings and transplanted into 11 cm pots on August 30, 2004. All colour characteristics were determined using the 2001 RHS colour chart and measured characteristics were based on ten plant measurements.
