The secondary colour on the upper side of the corolla lobes of 'SAKPXC010' differs from that of both reference varieties. The tertiary colour on the upper side of the corolla lobes of 'SAKPXC010' differs from that of 'SAKPXC005'. The upper side of the corolla lobes of 'SAKPXC010' have strong to very strong conspicuousness of veins whereas those of 'SAKPXC005' have medium conspicuousness of veins and those of 'SAKPXC008' have medium to strong conspicuousness of veins.

Origin & Breeding History: 'SAKPXC010' originated from a hybridization conducted in Kakegawa, Japan in July 2007. The hybridization was between the female parent, a proprietary hybrid Petunia line named 'AM6-99A-3' and the male parent, a proprietary hybrid Calibrachoa line named '5Bdw-7b-1A-1'. The new Petunia x Calibrachoa variety was selected through multiple generations based on flower colour and growth habit. In May 2008 and again in December 2008, it was confirmed that the new variety was distinct, uniform and stable.

Tests & Trials: Trials for 'SAKPXC010' were conducted in a polyhouse during the spring of 2013 in St. Thomas, Ontario. The trial included a total of 20 plants each of the candidate and reference varieties. All plants were grown from rooted cuttings and transplanted into 15 cm pots on April 25, 2013. Observations and measurements were taken from 10 plants of each variety on June 10, 2013. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
