Origin & Breeding History: 'Bonmadcrel' originated as part of a controlled breeding program from a cross conducted on September 3, 2003 at Yellow Rock in New South Wales, Australia.

The male parent was another proprietary breeding selection designated '03-12', characterized by its' single flower form, dark yellow flowers, light gray green foliage and open, uneven growth habit. Initial selection of 'Bonmadcrel' was made on May 4, 2004 based on its' flower colour, large flower size and compact growing habit.

Tests & Trials: Trials for 'Bonmadcrel' 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 5, 2007. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
