Initial selection and reproduction by vegetative cuttings first began in June, 2002.

Tests & Trials: The tests and trials for 'Balriorg' were conducted in a polyhouse at BioFlora Inc. in St. Thomas, Ontario during the spring of 2006. The trial included a total of 15 plants of both the candidate and reference varieties. All plants were grown from rooted cuttings and transplanted into 6 inch pots on April 26, 2006. Observations and measurements were taken from 10 plants of each variety on July 14, 2006. All colour measurements were determined using the 2001 Royal Horticultural Society (RHS) Colour Chart.
