Origin & Breeding History: The variety 'Sunny Yomistique' originated from a naturally occurring whole plant mutation of the parent variety 'Frosty Yomistique'. The variety was discovered and selected by the breeder in February 2007 in Fort Myers, Florida, USA. Selection was based on flower colour and form, flowering response time, excellent branching, uniform and compact habit, foliage characteristics and excellent post production longevity. Asexual reproduction by vegetative tip cuttings was first conducted in Fort Myers, Florida in May 2007.

Tests & Trials: Trials for 'Sunny Yomistique' were conducted in a greenhouse trial during the Fall of 2011 in Niagara-on-the-Lake, Ontario. On August 16, 2011, fifty unrooted cuttings were directly stuck into 11 cm pots, with 5 cuttings per pot. The trial included a total of 10 pots of each variety spaced 30 cm apart. Plants were pinched once prior to short day treatment. Observations and measurements were taken from 10 plants of the candidate variety on November 3, 2011 and the reference variety on November 8, 2011. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
