Origin & Breeding History: 'Sunbelsafu' originated from a cross between the female parent 'V14' and the male parent 'P30'. The cross took place in April 2002, at the Omi R&D Centre of Suntory Flowers Ltd. located in Higashiomi-shi, Shiga-ken, Japan. From this cross, 50 seedlings were selected in September 2002. The seedling designated as 'Sunbelsafu' was selected in September 2003 based on its flower colour and growth habit.

Tests & Trials: Trials for 'Sunbelsafu' were conducted during the summer of 2007, in a polyhouse, in St. Thomas, Ontario. The trial included 20 plants each of the candidate and reference varieties. All plants were grown from rooted cuttings and transplanted into 30 cm hanging baskets on May 1, 2007. Each hanging basket contained 4 cuttings with a total of 5 baskets per variety. Observations and measurements were taken from 10 plants of each variety (except plant height where 5 plants were measured) on July 3, 2007. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
