Origin & Breeding History: The variety 'SAKPXC009' was developed by the breeders Akinobu Ui and Shin Ishikawa, both employees of Sakata Seed Corporation, Japan. The new variety originated from an intergeneric cross made between two proprietary lines at the Kakegawa Research Station, Kakegawa, Japan in October 2004. The female parent is a proprietary Petunia line named '103K' and the male parent is a proprietary Calibrachoa line named '2B-106A-1'. After crossing the parent lines, 1600 ovules were removed from flowers on the female parent and cultured by standard ovule culture techniques. In March 2005, intergeneric hybrid plantlets were transplanted to soil-less media for greenhouse culture and acclimatization. From July to November 2005, the plants were asexually propagated through plant cuttings in Kakegawa, Japan and transplanted to an open field and evaluated for flower colour and plant growth habit. A single plant was selected for its pink flower colour, excellent blooming ability and semi-creeping growth habit. In June 2006, the breeder confirmed that the distinct characteristics of the selection named 'SAKPXC009' were fixed and stable.

Tests & Trials: Trials for 'SAKPXC009' were conducted in a polyhouse during the spring of 2012 in St. Thomas, Ontario. The trial included a total of 20 plants each of the candidate and reference variety. All plants were grown from rooted cuttings and transplanted into 40 cm pots on April 25, 2012. Observations and measurements were taken from 10 plants of each variety on May 28, 2012. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
