Origin & Breeding History: 'Bonscalib' originated from an open pollination made at Yellow Rock, New South Wales, Australia in 2003. The female parent was the proprietary variety 00-38.1 and the pollen was derived from a group of several proprietary varieties. Seeds from the open pollination were germinated and grown to maturity. One plant was selected on November 14, 2003 and propagated by cuttings. These were grown in potted trials from November 2003 to December 2004.

Tests & Trials: Trials for 'Bonscalib' were conducted during the spring of 2008 in a polyhouse at BioFlora Inc. in St. Thomas, Ontario. There were 15 plants each of the candidate and reference variety. The plants were grown from rooted cuttings which were transplanted into 15 cm pots on April 18, 2008. Observations and measurements were taken from 10 plants on June 13, 2008. All colour determinations were made using the 2001 Royal Horticulture Society (RHS) Colour Chart.
