Origin & Breeding History: The variety 'Bonmadcivy' originated from a cross conducted from June 2004 to July 2004 at Yellow Rock, New South Wales, Australia. The female parent was a proprietary selection designated O4-68, characterized by its single flower form, white flower colour, medium green foliage and compact upright growth habit. The male parent was the variety 'Bonmadcrel'. The initial selection was made on April 18, 2005 and propagation since that time has been through the use of vegetative cuttings. Selection criteria included time of flowering, plant habit, number of flowers, flower size and peduncle length.

Tests & Trials: Trials for 'Bonmadcivy' were conducted in a polyhouse during the spring of 2010 at BioFlora Inc. in St. Thomas, Ontario. The trials included a total of 15 plants each of the candidate and reference variety. All plants were grown from rooted cuttings and transplanted into 11 cm pots on April 30, 2010. Observations and measurements were taken from 10 plants of each variety on June 8, 2010. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
