Origin & Breeding History: 'Sunpurple' originated from a cross between the female parent 'Red Madness' and the male parent '70-200', conducted in April 2000, in Higashiomi-shi, Shiga-ken, Japan. In August 2000, 80 seedlings were obtained from the cross and evaluated in the greenhouse. One seedling was selected in October 2000, based on growth habit, flower size and flower colour. The new variety was subsequently named 'Sunpurple'.

Tests & Trials: Trials for 'Sunpurple' were conducted in a polyhouse during the spring of 2009 in St. Thomas, Ontario. The trial included a total of 15 plants each of the candidate and reference varieties. All plants were grown from rooted cuttings and transplanted into 15 cm pots on April 30, 2009. Observations and measurements were taken from 10 plants of each variety on May 27, 2009. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
