Origin & Breeding History: The variety 'Syeda Redda' originated from a controlled cross made in Alva, Florida, USA between January 2007 and March 2007. The female parent was a proprietary seedling designated 02-M061 and the male parent was the variety 'Yobonnie'. The resultant seed was collected and sown in a greenhouse in October 2007. A single plant from the progeny was selected by the breeder on March 25 2008 in Alva, Florida. The new variety was selected based on criteria for flower colour, early flowering and plant habit.

Tests & Trials: Trials for 'Syeda Redda' 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.
