Origin & Breeding History: 'VEAZ0015' originated from an open pollinated cross conducted in August 2007 by the breeder as part of a controlled breeding program in Enkhuizen, The Netherlands. The cross involved a proprietary line designated 'KO515-2' as the female parent and an unknown male parent. The resultant seed was collected and sown in a greenhouse in Enkhuizen in February 2008. In August 2008, 'VEAZ0015' was selected based on its flower colour and plant growth habit.

Tests & Trials: The PBR trials for 'VEAZ0015' were conducted in a polyhouse during the summer/fall of 2012 at BioFlora Inc. in St. Thomas, Ontario. The trial included a total of 20 plants each of the candidate and reference varieties. The plants were grown from rooted cuttings and transplanted into 15 cm pots on July 24, 2012. Observations and measurements were taken from 10 plants of each variety on September 18, 2012. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
