Origin & Breeding History: 'Sunvioda' originated from a cross between the female parent designated '0V-128-1' and the male parent designated '0V-40-1' which was conducted in April 2002 at the Omi R&D Center of Suntory Flowers Ltd. in Higashiomi-shi, Shiga-ken, Japan. In April 2003, one seedling was selected for its spreading growth habit, flower size and flower colour. This seedling was propagated by cuttings, planted in pots and subjected to trials beginning in October 2003. It was concluded that this variety is distinct, uniform and stable and as a result was named 'Sunvioda'.

Tests & Trials: Trials for 'Sunvioda' were conducted during the spring of 2008 at BioFlora Inc. in St. Thomas, Ontario. There were 15 plants of each variety. All plants were grown from rooted cuttings and transplanted into 11.5 cm pots on March 17, 2007. Observations and measurements were taken from 10 plants or parts of plants of each variety on May 1, 2008. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
