Origin & Breeding History: 'Yomistique' is a product of a planned breeding program conducted by the breeder, Mrs. Wendy R. Bergman, an employee of Yoder Brothers, Inc. in Barberton, Ohio, USA. It originated from a cross between proprietary Chrysanthemum seedling selection designated 'YB-6500' as the female parent and another proprietary Chrysanthemum seedling selection designated 'YB-4714' as the male parent. This cross was conducted by the breeder in August 1997, in Salinas, California, USA. 'Yomistique' was discovered and selected in December 1998, as a single flowering plant among the progeny of the stated cross growing in a controlled environment in Fort Myers, Florida, USA. The selection of this plant was based on its uniform plant growth habit, desirable inflorescence form and floret colours, fast response time and excellent post-production longevity. Asexual reproduction of 'Yomistique' by vegetative tip cuttings was first conducted in Fort Myers, Florida, USA in March 1999.

Tests & Trials: Trials for 'Yomistique' were conducted in the fall of 2007 at Yoder Canada Ltd. in Leamington, Ontario. They were performed under greenhouse conditions similar to those used in commercial Chrysanthemum production. 40 unrooted cuttings per variety were directly stuck into 15 cm pots with 4 cuttings per pot and 10 pots per variety. The pots were spaced 30 cm apart. The plants were pinched once prior to short day treatment. All plants had the central bud removed. Observations and measurements were taken from 10 plants of each variety on October 29, 2007. All colour determinations were made using the 2001 Royal Horticulture Society (RHS) Colour Chart.
