Origin & Breeding History: 'Silt Cher' originated from a hybrid cross conducted by the breeder Jolanda Krassenburg, an employee of Goldsmith Seeds Europe, Andijk, The Netherlands, as part of a planned breeding program in April 2003. The cross was between the female parent 'ID03-25-2' and the male parent 'ID03-29-2'. The resultant seed was sown in June 2003. In August 2003, a single plant was selected by the breeder based on flower colour, flower quality and plant growth habit.

Tests & Trials: Trials for 'Silt Cher' were conducted in a polyhouse during the summer of 2008 in St. Thomas, Ontario. Trials included 15 plants each of the candidate and reference varieties. Rooted cuttings were transplanted into 15 cm pots on April 25, 2008. Observations and measurements were taken from 10 plants of each variety on June 23, 2008. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
