The female parent was a proprietary seedling designated 01-M300 RD 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 2005. A single plant from the progeny was selected by the breeder on October 8, 2005 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 'Syaid Redfi' 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 September 21, 2011. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
