Origin & Breeding History: 'Sunrenicopalave' originated from a cross between Torenia variety 'Cyclone Burgundy' as the female parent and Torenia concolor as the male parent. The cross was conducted in July 2002 at the Omi R & D Center of Suntory Flowers Ltd., located in Yokaichi-shi, Shiga-ken, Japan. On the 14th day after pollination, the ovules were transfered to embryo culture on MS medium. In September 2002, two lines were obtained and acclimated to pot culture. The resulting two plants were propagated by cutting and grown in pots for greenhouse trials. In December 2002, one of the plants was selected based on its' flower colour and growth habit. This selection was subjected to flower pot and bedding trials from September to May 2003. Upon examination of the botanical characteristics of this plant, it became known as 'Sunrenicopalave'.

Tests & Trials: Trials for 'Sunrenicopalave' were conducted in a poly-house during the spring of 2007 at BioFlora Inc. in St. Thomas, Ontario. The trial included a total of fifteen (15) plants per variety. All plants were grown from rooted cuttings and transplanted into 11.5 cm pots on May 9, 2007. Observations and measurements were taken from ten (10) plants or parts of plants on June 14, 2007. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
