Seedlings obtained from the cross were grown in pots in a glasshouse and evaluated. Some seedlings were selected based on growth habit, flower size and colour. The selected plants were propagated by cuttings and grown in trials. In 2006, one plant was chosen and named 'Sunmecakira'.
Tests & Trials: Trials for 'Sunmecakira' were conducted in a polyhouse during the summer of 2009 in St. Thomas, Ontario. The trial included a total of 15 plants of each of the candidate and reference varieties. All plants were grown from rooted cuttings and transplanted into 15 cm pots on May 5, 2009. Observations and measurements were taken from 10 plants of each variety on June 11, 2009. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
