The objective of the breeding program was to develop a series of proprietary portulaca varieties unique in its characteristics from other portulaca varieties. Initial selection and reproduction by vegetative cuttings first began in June, 2002.

Tests & Trials: The tests and trials for 'Balrioscar' 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 13-14, 2006. All colour measurements were determined using the 2001 Royal Horticultural Society (RHS) Colour Chart.
