The new variety was selected in the summer of 2006 from the population of seedlings based on plant growth habit and flower colour.

The trial consisted of 15 plants each of the candidate and reference varieties with one plant per pot. The pots were 22 cm in diameter and were spaced approximately 45 cm apart. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
