Origin & Breeding History: 'CBRZ0004' originated from a cross pollination conducted in Gilroy, California, United States in September 2007 between the female parent identified as '1808-1' and pollen from the male parent identified as '1777-1'. The variety 'CBRZ0004' was bred and developed by the breeder Robert Pierce, an employee of Syngenta Flowers Inc., in Gilroy as part of a controlled breeding program. The resultant seed from the cross was collected and sown in a greenhouse in Gilroy in July 2008. In September 2008, a single plant was selected based on flower colour and plant habit.

Tests & Trials: Trials for 'CBRZ0004' were conducted during the summer 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 30 cm hanging baskets on May 15, 2012. Each basket contained 4 cuttings with a total of 5 baskets per variety. All baskets were flowered in an outdoor area. Observations and measurements were taken from 10 plants of each variety on June 25, 2012. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
