Just before opening, the colour of the outer side of the flower bud is dark purple red for 'CIDZ0002' while it is light blue violet with violet tones for 'Yowinnipeg'. The curvature along the longitudinal axis of a ray floret from the inner row is strongly incurved for 'CIDZ0002' while the ray floret of 'Yowinnipeg' is weakly incurved. The colour of the inner side of the ray floret is dark brown to dark purple red for 'CIDZ0002' while it is blue pink with lighter blue pink margins for 'Yowinnipeg'.

Origin & Breeding History: 'CIDZ0002' originated from a controlled cross-pollination conducted in November 1999, in Salinas, California, USA, as part of a controlled breeding program of Syngenta Flowers, Inc. The cross involved a proprietary line designated 'YB-6132' as the female parent, and a proprietary line designated 'YB-6606' as the male parent. The resultant seed was sown in a greenhouse in July 2000. 'CIDZ0002' was selected as a single plant from the progeny in November 2000 by the breeder, Wendy R. Bergman, in Alva, Florida, USA, based on its flower colour, plant growth habit, and production characteristics.

Tests & Trials: The trial for 'CIDZ0002' was conducted in the fall of 2012 at Meyers Fruit Farm in Niagara on the Lake, Ontario. Flowering trials were conducted under greenhouse conditions similar to those used in commercial Chrysanthemum production. 50 unrooted cuttings were stuck into 15 cm pots on August 18, 2012. There were 5 cuttings per pot and the pots were spaced 30 cm apart. The plants were pinched once prior to short day treatment. Observations and measurements were taken from 10 plants, or parts of plants, of the candidate variety and 9 plants, or parts of plants, of the reference variety on November 14, 2012. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
