Origin & Breeding History: 'PEQZ0003' was bred and developed by the breeder, Mitchell Hanes, as part of a controlled breeding program. It originated from a cross pollination between a proprietary line with rose coloured flowers designated '10521-2' as the female parent, and a proprietary line with blush rose coloured flowers designated '105201' as the male parent. This cross was conducted in Gilroy, California, United States in February 2007. The resultant seed was collected and sown in a greenhouse in Gilroy in August 2007. In December 2007, a single plant was selected using flower colour, and plant habit as the selection criteria. This selection was named 'PEQZ0003'.

Tests & Trials: Trials for 'PEQZ0003' were conducted in a polyhouse during the spring and summer of 2012 at BioFlora Inc. in St. Thomas, Ontario. There were a total of 20 plants each of the candidate and reference varieties. All plants were grown from rooted cuttings and transplanted into 15 cm shallow pots on May 2, 2012. Observations and measurements were taken from 10 plants of each variety on June 19, 2012. All colour determinations were made using the 2007 Royal Horticulture Society (RHS) Colour Chart.
