Origin & Breeding History: 'Sunnicopaho' originated from a cross made in the summer of 2003 between two proprietary Nierembergia sp. selections; 'NB13' as the female parent and 'NS1' as the male parent. The cross was conducted at the Omi R&D Center of Suntory Flowers Ltd. in Shiga, Japan. The resulting seedlings were grown in pots in a glasshouse for evaluation. In 2004, several seedlings were selected based on their plant shape and flower colour and then propagated vegetatively to be grown in pots. A trial was carried out in 2005 at Higachiomi-shi in Shiga, Japan to examine the botanical characteristics of these selections in comparison to similar varieties. In October 2005, it was concluded that one of the Nierembergia plants was distinguishable from all other varieties and also found to be uniform and stable in its characteristics. It was named 'Sunnicopaho'.

Tests & Trials: Trials for 'Sunnicopaho' were conducted in a polyhouse during the summer of 2009 at BioFlora Inc. in St. Thomas, Ontario. There were 15 plants per variety. All plants were grown from rooted liners and transplanted into 15 cm pots on May 5, 2009. Observations and measurements were taken from 10 plants or parts of plants of each variety on June 10, 2009. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Charts.
