The resultant seed was sown in a greenhouse in September 2003 and in December 2003, a single plant was selected from the progeny based on large flower size and plant growth habit.

Tests & Trials: Trials for 'Ri Reeda' were conducted during the spring of 2008 in a polyhouse at BioFlora Inc. in St. Thomas, Ontario. There were 15 plants each of the candidate and reference varieties. The plants were grown from rooted cuttings which were transplanted into 15 cm pots on May 13, 2008. Observations and measurements were taken from 10 plants on June 30, 2008. All colour determinations were made using the 2001 Royal Horticulture Society (RHS) Colour Chart.
