Origin & Breeding History: The variety 'SAKIMP021' originated from a hybridization between two proprietary breeding lines, made in June 2005 at the Misato Research Station in Misato, Japan. The resultant F1 progeny were evaluated in an open field trial and a single plant selection was made based on criteria for flower colour, strong root system and vigorous plant growth habit. From May to August 2006, the selection was evaluated in the field in Misato, Japan. Shoot tip cuttings of the selection were sent to Salinas, California where the plants were grown and evaluated for stability traits. The selection, subsequently named 'SAKIMP021', was found to have unique characteristics that reproduce true to type in successive generations of asexual propagation.
Tests & Trials: Trials for 'SAKIMP021' were conducted in a polyhouse during the spring of 2010 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 21, 2010. Observations and measurements were taken from 10 plants of each variety on June 21, 2010. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
