Origin & Breeding History: The variety 'SAKPXC007' 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 2005. Intergeneric hybrid plantlets were obtained using standard ovule culture. In March 2006, 10 hybrid plantlets were transplanted to soil-less media for greenhouse culture and acclimatization. In June 2006, 10 plants out of 10 hybrid lines were vegetatively propagated to produce rooted cuttings. In July 2006, the 10 plants were transplanted to an open field and evaluated for flower colour and plant growth habit. In December 2006, one plant which had a rosy-red flower colour, good blooming ability and mounding plant habit was selected and vegetatively propagated. In March 2007, 10 cuttings were evaluated in an open field through to June 2007. In June 2007, the breeder confirmed that the distinct characteristics of the selection named 'SAKPXC007' were fixed and stable.

Tests & Trials: Trials for 'SAKPXC007' 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.
