Origin & Breeding History: 'SAKPET001' originated from a hybridization between the female parent proprietary breeding line '9S-351-3A' and the male parent proprietary breeding line '03BCR-14A'. The new petunia was bred and developed by the breeder Akinobu Ui, in 2005, in Kakegawa, Japan. Selection of 'SAKPET001' was based on flower colour and growth habit. The variety was finally selected and named in October 2006.

Tests & Trials: Trials for 'SAKPET001' were conducted in a polyhouse during the spring of 2010 in St. Thomas, Ontario. The trial included a total of 15 plants each of the candidate and reference varieties. 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 May 26, 2010. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
