Origin & Breeding History: 'Kakegawa S89' was developed by the breeder, Akinobu Ui, an employee of Sakata Seed Corporation, Japan. It originated from a hybridization between a proprietary hybrid Calibrachoa line and a proprietary hybrid Petunia line made in May 2003 in Kakegawa, Japan. In December 2003, 10 intergeneric hybrid plantlets were transplanted to soil-less media for greenhouse culture and acclimatization. In March 2004, 7 of the 10 plantlets were vegetatively propagated to produce rooted cuttings. In April 2004, these were transplanted to an open field and evaluated until July 2004 for flower colour and plant growth habit. 'Kakegawa S89' was selected in August 2004 based on its bright pinkish red flowers with yellow corolla throat and mounding plant growth habit. Ten (10) cuttings of 'Kakegawa S89' were further evaluated in open field trials from September to November 2004. These trials were used to confirm that the distinctive characteristics of 'Kakegawa S89' are fixed and stable.

Tests & Trials: Trials for 'Kakegawa S89' were conducted in a poly-house during the summer of 2007 at BioFlora Inc. in St. Thomas, Ontario. The trial included a total of fifteen (15) plants per variety. All plants were grown from rooted cuttings and transplanted into 11.5 cm pots on July 10, 2007. Observations and measurements were taken from ten (10) plants or parts of plants on August 30, 2007. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
