Origin & Breeding History: 'Sunnicopadibu' originated from a cross made in the summer of 2003 between the female parent designated 'N121' and the male parent 'NB18' at the Omi R & D Center of Suntory Flowers Ltd. located in Higashiomi-shi, Shiga-ken, Japan. The resultant seeds were sown and grown in pots. In October 2004, several seedlings were selected based on their plant shape and flower colour, propagated by cuttings and subjected to flower potting and bedding trials in 2005. In October 2005, 'Sunnicopadibu' was finally selected.

Tests & Trials: Trials for 'Sunnicopadibu' were conducted in a polyhouse during the summer of 2008 at BioFlora Inc. in St. Thomas, Ontario. The trial included a total of 15 plants per variety. All plants were grown from rooted cuttings and transplanted into 15 cm pots on April 16, 2008. Measured characteristics were based on measurments taken from 10 plants or parts of plants on June 10, 2008. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
