Origin & Breeding History: 'Sunsurf Depausa' originated as a controlled pollination conducted in an isolated area in March 2008 between the female parent variety 'BW1', a proprietary selection, and the male parent 'PF411-5', a proprietary selection. Seeds from the cross were germinated and grown to maturity. One plant was selected by the breeder in October 2008, at Miyazaki-shi, Miyazaki, Japan based on growth habit, flower size and flower colour. The new plant was propagated by cuttings and grown in pots. A trial was carried out from April to September 2009 where the botanical characteristics of the variety were examined. After determining that the new variety was distinguishable from any other varieties, and uniform and stable in its characteristics, the new variety was named 'Sunsurf Depausa'.

Tests & Trials: Trials for 'Sunsurf Depausa' were conducted in a polyhouse during the spring of 2013 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 April 10, 2013. Observations and measurements were taken from 10 plants of each variety on May 14, 2013. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
