Origin & Breeding History: 'Viking' is a product from a planned breeding program conducted by the breeder, Arie Blom, in the Netherlands. It originated from a controlled cross between a proprietary seedling designated 'Ca 402-01' as the female parent, and a proprietary seedling designated 'Ca 406-01' as the male parent. The cross was conducted in May 2004 in IJsselstein, Netherlands. In June 2007, 'Viking' was selected by the breeder in Zuidwolde, Netherlands based on its plant growth habit, non-invasive quality, flower sterility, flower size, and flower colour. Asexual reproduction of 'Viking' by tissue culture was first conducted in October 2007 in Enkhuizen, Netherlands.
Tests & Trials: The trial of 'Viking' was conducted as an outdoor container trial during the summer of 2013, at BioFlora Inc. in St. Thomas, Ontario. It included a total of 15 plants of the candidate variety and 11 plants of the reference variety. All plants were grown from rooted cuttings transplanted to 4.5 litre containers in October 2012. Observations and measurements were taken from 10 plants or parts of plants of each variety on June 12, 2013. All colour determinations were made using the 2007 Royal Horticulture Society (RHS) Colour Chart.
