Origin & Breeding History: 'Bonmadcrio' originated as part of a controlled breeding program from a cross conducted on August 15, 2003 at Yellow Rock in New South Wales, Australia. The female parent was a priority breeding selection designated '03-75', characterized by its' anemone flower form, deep pink flowers with white ring of centre florets, medium green foliage and upright, uneven growth habit. The male parent was another proprietary breeding selection designated '03-36', characterized by its' single flower form, dark red flowers, medium green foliage and compact growth habit. Initial selection of 'Bonmadcrio' was made on May 4, 2004 based on its' flower colour, flower form, flower size, early flowering and less fading of flower colour in comparison to other varieties with similar colouring.

Tests & Trials: Trials for 'Bonmadcrio' 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 June 8, 2007. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
