Origin & Breeding History: 'SAKPXC005' was developed by the breeders Akinobu Ui and Shin Ishikawa, both employees of Sakata Seed Corporation, Japan. The new variety originated from a hybridization made by the breeders in October 2004 in Kakegawa, Japan. The female parent was a proprietary hybrid Petunia line and the male parent was a proprietary Calibrachoa line. In April 2005, the selected plant was vegetatively propagated to produce rooted cuttings and was transplanted to an open field. From April to July 2005, it was evaluated for flower colour and plant growth habit. A single plant, named 'SAKPXC005' was selected based on flower colour, flower size and plant habit. From August to November 2005, 'SAKPXC005' was vegetatively propagated and transplanted into a field. In November 2005, the new variety was found to have unique characteristics that are fixed and stable.

Tests & Trials: Trials for 'SAKPXC005' were conducted in a polyhouse during the spring of 2010 in St. Thomas, Ontario. The trials included a total of 15 plants of each variety. All plants were grown from rooted cuttings and transplanted into 15 cm pots on April 27, 2010. Observations and measurements were taken from 10 plants of each variety on June 3, 2010. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
