Origin & Breeding History: 'DVPazurri' originated from a controlled cross between the variety 'Oiseau Bleu' as the female parent and an unnamed chromosome doubled seedling as the male parent in the summer of 2000 in Melle, Belgium. It was selected in September 2003 based on strong growth, rich flower colour and sterility. 'DVPazurri' was evaluated for several years at the breeders institute, Instituut Voor Landbouw - En Visserijonderzoek Eenheid Plant (ILVO), Belgium prior to commercialization in 2008.
Tests & Trials: Trials were conducted as an outdoor container trial during the summer of 2011 in St. Thomas, Ontario. The trial included a total of 10 plants/shrubs of each variety. All plants/shrubs were grown from 5.7 cm liners potted into 7.6 liter containers in the spring of 2009. Observations and measurements were taken from 10 plants/shrubs of each variety in June of 2011. All colour measurements were made using the 2007 RHS Colour Chart.
