The resultant seed was grown in a greenhouse in October 2005 with a single plant being selected in January 2006 based upon flower colour and plant habit.

Tests & Trials: Tests and trials were conducted in a polyhouse during the spring of 2008 in St. Thomas, Ontario. There were 15 plants of each variety, individually grown in 11 cm pots. Observations and measurements were taken from 10 plants of each variety. All colour measurements were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
