Origin & Breeding History: The variety 'VEAZ0012' originated from an open pollinated cross, made in Enkhuizen, Netherlands in August 2008. The female parent was a proprietary line, designated LO510-4, characterized by its burgundy and white bicoloured flower. The male parent was unknown. The resultant seed was collected and sown in a greenhouse in Enkhuizen in February 2009. In August 2009, a single plant was selected based on criteria for flower colour and plant habit.
Tests & Trials: Trials for 'VEAZ0012' were conducted in a polyhouse during the spring of 2012 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 May 2, 2012. Observations and measurements were taken from 10 plants of each variety on June 7, 2012. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
