Origin & Breeding History: 'Balrioapt' arose from the self-pollination of the variety, 'Wild Fire Bronze' conducted in January 2002 at Dulce Nombre de Cartago, Costa Rica. 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 'Balrioapt' 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.
