Origin & Breeding History: The variety 'Bonmadrosepi' originated from a controlled cross conducted in August 2005 in New South Wales, Australia. The female parent was a proprietary selection designated 04-36, characterized by its anemone type flower form, medium pink flower colour, medium green foliage and slightly vigorous compact, mounded growth habit. The male parent was a bulk pollen mix of proprietary breeding selections characterized by their single to double flower form, medium to dark pink flower colours, medium green foliage colour and low to moderately vigorous compact, mounded growth habit. The initial selection was made on August, 2006 and propagation since that time has been through the use of vegetative cuttings. Selection criteria included flowering time, flower number and size, flower stem length and overall habit and performance that matched the Madeira series.

Tests & Trials: Trials for 'Bonmadrosepi' were conducted in a polyhouse during the summer of 2011 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 15 cm pots on April 29, 2011. Observations and measurements were taken from 10 plants of each variety on June 24, 2011. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
