Origin & Breeding History: 'SAKIMP015' originated from a hybridization between the female parent variety 'NC-1H' and the male parent variety 'NG-01H-9B' conducted by the breeders Moriya Kawashima and Yoneo Kobayashi in January 2003 in Misato, Japan. The resultant progeny were grown in a field trial in 2004, in Misato, Japan and were evaluated for flower colour, strength of root system and plant growth habit. Based on these criteria a single plant was selected and vegetatively propagated. After being evaluated in a field trial from May to August of 2005, the new variety was shipped to Salinas, California where it was propagated from shoot-tip cuttings and reevaluated for stability of traits. The new variety was found to reproduce true to type and was subsequently named 'SAKIMP015'.

Tests & Trials: Trials for 'SAKIMP015' were conducted in a polyhouse during the summer of 2008 in St. Thomas, Ontario. Trials included 15 plants each of the candidate and reference varieties. Rooted cuttings were transplanted into 15 cm pots on April 29, 2008. Observations and measurements were taken from 10 plants of each variety on July 3, 2008. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
