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.
Tests & Trials: The tests and trials for 'Keipawhihis' were conducted in a polyhouse at BioFlora in St. Thomas, Ontario in the spring of 2006. The trials included 15 plants of each variety.

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