Origin & Breeding History: 'Bonmadcher' originated as part of a controlled breeding program from a cross conducted in July 2003 at Yellow Rock in New South Wales, Australia. The female parent was a priority breeding selection designated '03-26', characterized by its' semi-double flower form, medium pink flowers, medium green foliage and mounded growth habit. The male parent consisted of a combination of many proprietary breeding selections designated '03-21' to '03-49', '03-57', 03-133' and '03-148', all characterized by their semi-double flower form, red and pink flowers, various shades of green foliage and various growth habits. Initial selection of 'Bonmadcher' was made in July 2004 based on its' deep flower colour, large flower size, early flowering and less fading of flower colour in comparison to varieties with similar colouring.

Tests & Trials: Trials for 'Bonmadcher' were conducted in a polyhouse during the spring of 2007 at BioFlora Inc. in St. Thomas, Ontario. The trials included 15 plants per variety. Rooted cuttings were transplanted into 15 cm pots on March 23, 2007. Measured characteristics were based on measurements taken from 10 plants or parts of plants on May 25, 2007. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
