Origin & Breeding History: 'Sunrenipink' originated from the heavy ion irradiation of in-vitro meristems of a proprietary torenia selection designated TH1. The irradiation was completed in 2005 at the Institute of Physical and Chemical Research in Japan. All shoots developed from the irradiated meristems were grown in pots in the glasshouse. In March 2006, one plant was selected based on petal colour and growth habit. The selected plant was propagated by cuttings and grown in pot trials from April to October 2007 at Higashiomi-shi, Shiga, Japan.

Tests & Trials: Trials for 'Sunrenipink' were conducted in a polyhouse during the spring of 2009 at BioFlora Inc. in St. Thomas, Ontario. The trial included a total of fifteen plants per variety. All plants were grown from rooted cuttings and transplanted into 11 cm pots on May 7, 2009. Observations and measurements were taken from ten plants or parts of plants on July 30, 2009. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
