Origin & Breeding History: 'SAKIMP025' originated from a hybridization that was conducted in Misato, Japan in October 2008, between the female parent line 'NF-572A' and the male parent line 'NG-422'. The resultant first generation seed was sown and plants were evaluated in an open field trial in Misato, Japan. A single plant was selected based on flower colour, strength of the root system and growth habit. The selection was vegetatively propagated and evaluated in an open field in Misato, Japan from May to August 2010. The selection was subsequently named 'SAKIMP025'.

Tests & Trials: Trials for 'SAKIMP025' were conducted in a polyhouse during the spring of 2013 in St. Thomas, Ontario. Trials included 20 plants each of the candidate and reference varieties. Rooted cuttings were transplanted into 15 cm pots on April 4, 2013. Observations and measurements were taken from 10 plants of each variety on June 11, 2013. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
