Origin & Breeding History: 'Kirimaji Double Red' originated from a controlled cross made by the breeder Mr. Kiyoto Haba in November 2006, at the Plant Research Center, in Tochigi, Japan. The new Petunia variety was the result of crossing two unnamed proprietary seedlings and was selected as a single plant from the resultant progeny in September 2007 in De Lier, The Netherlands. 'Kirimaji Double Red' was selected based on flower colour, flower form, plant vigour and plant growth habit. Asexual reproduction by cuttings was first conducted in the Spring of 2008 in De Lier, The Netherlands.

Tests & Trials: Trials for 'Kirimaji Double Red' 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 and transplanted into 15 cm pots on April 27, 2010. Observations and measurements were taken from 10 plants of each variety on June 7, 2010. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
