Origin & Breeding History: The variety 'Syelect Ambe' originated from a controlled cross made in Alva, Florida, USA in February 2007. The female parent was a proprietary seedling designated 04-M266-YL DC and the male parent was the variety 'Yoursula'. The resultant seed was collected and sown in a greenhouse in June 2007. A single plant from the progeny was selected by the breeder on October 12, 2007 in Alva, Florida. The new variety was selected based on criteria for flower colour, flower size, early flowering and plant habit.

Tests & Trials: Trials for 'Syelect Ambe' 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 the candidate variety on September 14, 2011 and the reference variety on September 28, 2011. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
