Origin & Breeding History: 'SAKPXC006' was developed by the breeders Akinobu Ui, Shin Ishikawa and Niels G. Kristensen, all employees of Sakata Seed Corporation, Japan. The new variety originated from a hybridization made by the breeders in May 2003 in Kakegawa, Japan. The female parent was a proprietary hybrid Petunia line and the male parent was a proprietary Calibrachoa line. In March 2004, the selections were vegetatively propagated to produce rooted cuttings and were transplanted to an open field. From April to July 2004, the selections were evaluated for flower colour and plant growth habit. In July 2004, a single plant was selected with purple flowers, medium to large sized flowers and a semi-creeping plant habit. The selection was vegetatively propagated. In January 2007, at Petersminde Nursery, in Aabyhoej, Denmark, a mutation was discovered from the selected plant. This plant was selected based on flower colour. From January to October 2007, the new plant was propagated and transplanted in Aabyhoej, Denmark. In November 2007, the new variety called 'SAKPXC006' was found to have unique characteristics that are fixed and stable.

Tests & Trials: Trials for 'SAKPXC006' 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.
