Origin & Breeding History: 'Bonbrapi' originated from a controlled pollination between the proprietary Brachyscome formosa variety '00-126.2' with the Brachyscome variety '00-52' conducted in Yellow Rock, Australia, in 2004. Seeds from the cross were germinated and grown to maturity. One plant was selected by the breeder on July 12, 2005 based on flower size, flower colour, leaf size, leaf form and leaf colour. The selected plant was propagated by cuttings and grown in pots. A trial was carried out from July 2005 to December 2006 in order to examine the botanical characteristics of the plant. As a result, it was concluded that this Brachyscome plant was distiguishable from any other varieties and it was named 'Bonbrapi'.

Tests & Trials: Trials for 'Bonbrapi' were conducted in a polyhouse during the spring 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 10 cm pots on May 17, 2010. Observations and measurements were taken from 10 plants of each variety on June 21, 2010. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
