Origin & Breeding History: 'SYEP23203' originated from a cross pollination conducted in Hillscheid, Germany in June 2003 between the female parent proprietary seedling identified as S90-1901-1 and pollen from the male parent variety 'Fispoin 7776'. The resultant seed was collected and sown in a greenhouse in Hillscheid, Germany in February 2004. A single plant was selected by the breeder in December 2004 based on bract colour, inflorescence size, foliage colour, branch strength and plant habit. The new variety was tested in trials at greenhouses in Hillscheid, Germany, Enkhuzein, The Netherlands and Boulder, Colorado, USA, in April 2005. Further evaluations in greenhouse trials were conducted in the fall of 2007 and 2008.

Tests & Trials: Trials for 'SYEP23203' were conducted in a greenhouse in St. Catharines, Ontario. Trials included 25 plants each of the candidate and reference variety. All plants were grown from rooted cuttings and transplanted into 15 cm pots on July 30, 2012. Pots were spaced 27 cm apart, from the pot centre. Observations and measurements were taken from 10 plants of each variety on December 4, 2012. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
