Origin & Breeding History: The variety 'Symarj Col' originated from a controlled cross made in Alva, Florida, USA on October 15 2005. The female parent was a proprietary seedling designated 03-M341-PK DC and the male parent was a proprietary seedling designated 00-M401-CO DU. The resultant seed was collected and sown in a greenhouse in June 2006. A single plant from the progeny was selected by the breeder on November 8, 2006 in Alva, Florida. The new variety was selected based on criteria for flower colour, flower type, flower size, early flowering, response time and plant habit.

Tests & Trials: Trials for 'Symarj Col' were conducted in an outdoor irrigated trial during the summer of 2011 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 20 cm pots on June 23, 2011. Observations and measurements were taken from 10 plants of each variety on October 4, 2011. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
