Origin & Breeding History: 'Currant Yomistique' originated from a naturally occurring whole plant mutation of the parent variety 'Yomistique', discovered and developed by the breeder, Mrs. Wendy Bergman, in December 2004 in Fort Myers, Florida, USA. 'Currant Yomistique' was selected based on its compact growth habit, excellent branching, appearance of foliage, flowering response time, flower form, flower colour and excellent post production quality. Asexual reproduction of the variety by vegetative tip cuttings was first conducted in Fort Myers, Florida, USA in March 2005.

Tests & Trials: Trials for 'Currant Yomistique' were conducted in Leamington, Ontario, in the fall of 2009. Flowering trials were performed under greenhouse conditions similar to those used in commercial chrysanthemum production. Forty unrooted cuttings of both the candidate and reference variety were directly stuck into 15 cm pots, with 4 cuttings per pot, 10 pots per variety, planted on August 24, 2009. 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 6, 2009. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
