The male parent was Argyranthemum variety 'Ohmadleva' (Madeira White), characterized by its' single flower form, white flowers, medium gray green foliage and compact, mounded growth habit. Initial selection of 'Bonmadcrepe' was made on May 18, 2004 based on its' flower size and early flowering combined with other good, general characteristics.

Tests & Trials: Trials for 'Bonmadcrepe' 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.
