Origin & Breeding History: 'Balbreblus' originated from a cross pollination between the female parent 'Inneuphdia' and the male parent 'Flame' conducted in June 2006 at Arroyo Grande, California, USA as part of a controlled breeding program. The initial selection of 'Balbreblus' was made in December 2006 based on variegated foliage and bract colours. Asexual propagation since that time has been through the use of vegetative cuttings.

Tests & Trials: Trials for 'Balbreblus' were conducted in a polyhouse during the summer of 2010, in St. Thomas, Ontario. The trial included a total of 15 plants each of the candidate and reference varieties. All plants were grown from rooted cuttings and transplanted into 12 cm pots on April 29, 2010. Observations and measurements were taken from 10 plants of each variety on June 4, 2010. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
