Origin & Breeding History: 'Silte Ror07' originated from a cross conducted at Goldsmith Seeds Europe, Andijk, The Netherlands, as part of a planned pedigree breeding program in June 2004. The cross was between the female parent 'ID03-20-5' and the male parent 'ID03-20-7' both proprietary lines. The resultant seed was sown in September 2004. In December 2004, a single plant was selected based on bi-colour flower pattern in combination with plant growth habit.

Tests & Trials: Trials for 'Silte Ror07' 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.
