Origin & Breeding History: 'Kirifu-24' originated from a cross conducted during May 2001, in Tochigi, Japan. The cross was between the female parent 'Kirifu Compact Blue' and the male parent a Calibrachoa pygmaea plant. The initial selection of 'Kirifu-24' was made in September 2001 based on its plant growth habit, vigor, branching habit, time of flowering, sterility and tolerance to weather extremes. The variety has been maintained since October 2001 through the use of vegetative cuttings.
Tests & Trials: Trials for 'Kirfu-24' were conducted during the summer of 2007, in a polyhouse, in St. Thomas, Ontario. The trial included 15 plants each of the candidate and reference varieties. All plants were grown from rooted cuttings and transplanted into 11 cm pots on April 30, 2007. Observations and measurements were taken from 10 plants of each variety on June 21, 2007. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
