Origin & Breeding History: 'Sunrenikonho' originated from a controlled pollination of the proprietary Torenia variety 'TP-1' with the Torenia variety 'TFOEx-W' in an isolated area in July 2006. Seeds from the pollination were germinated and grown to maturity. One plant was selected by the breeder on March 2007, in a controlled environment at Higashiomi, Shiga, Japan. The selected plant was propagated by cuttings and grown in pots. The new variety of Torenia was found to be distinguishable from any other varieties and was named 'Sunrenikonho'.

Tests & Trials: Trials for 'Sunrenikonho' were conducted in a polyhouse during the spring of 2010, 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 transplanted into 12 cm pots on May 18, 2010. Observations and measurements were taken from 10 plants of each variety on June 17, 2010. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
