Origin & Breeding History: The variety 'Sunrekobuho' originated from a controlled pollination, made in July 2007, at Higashiom, Shiga, Japan. The female parent was a proprietary torenia variety designated 'TP-1' and the male parent was a proprietary torenia variety designated 'TFOEx-BW'. Seeds from the pollination were germinated and grown to maturity. One plant was selected by the breeder in March 2008, in a controlled environment at Higashiom, Shiga, Japan. The selected plant was propagated by cuttings and grown in a pot trial from May to September 2008. The new variety of torenia was found to be distinguishable from any other varieties and was named 'Sunrekobuho'.

Tests & Trials: Trials for 'Sunrekobuho' were conducted in a polyhouse during the spring of 2011, 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 11 cm pots on April 29, 2011. Observations and measurements were taken from 10 plants of each variety on June 7, 2011. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
