In April 2002, 100 seedlings were obtained from the cross and grown in pots in the glasshouse for evaluation. In July 2002, one seedling was selected based on its growth habit, flower size and flower colour.

All colour measurements were made using the 2001 Royal Horticultural Society Colour Chart.
