Origin & Breeding History: 'Dark Bronze Cherie' originated from a naturally occurring whole plant mutation of the parent variety 'Apricot Cherie'. The new variety was discovered and selected by the breeder, Annette Nancy McGaughey, in February 2003, in Brantford, Ontario, Canada. Selection of 'Dark Bronze Cherie' was based on plant growth habit, inflorescence type, floret and foliage colour, response time and profuse flower production. Asexual reproduction of the variety by vegetative tip cuttings was first conducted in Brantford, Ontario, Canada in May 2003.

Tests & Trials: Trials for 'Dark Bronze Cherie' were conducted in Leamington, Ontario, in the fall of 2008. Flowering trials were performed under greenhouse conditions similar to those used in commercial chrysanthemum production. Forty unrooted cuttings of both the candidate and reference varieties were directly stuck into 15 cm pots, with 4 cuttings per pot, 10 pots per variety, planted August 18, 2008. Plants were spaced 30 cm apart and pinched once prior to short day treatment. All plants had the center bud removed. Observations and measurements were taken from 10 plants of each variety on November 3, 2008. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
