The flower head of 'CIDZ0033' is single type with a low height whereas the flower head of 'Regal Yoirvine' is semi-double type with a very low height. The predominant type of ray floret is spatulate for 'CIDZ0033' while for 'Regal Yoirvine', the ray floret type is ligulate. 'CIDZ0033' has a longer corolla tube of the ray floret than 'Regal Yoirvine'. The colour of the inner side of the ray floret of 'CIDZ0033' is purple red with dark purple red, mottled overcolour whereas the inner side of the ray floret of 'Regal Yoirvine' is blue pink with purple overcolour.

Origin & Breeding History: 'CIDZ0033' originated from a controlled cross-pollination conducted in July 2007, in Bogota, Columbia, as part of a controlled breeding program of Syngenta Flowers, Inc. The cross involved variety 'Yobaldwin' (Baldwin) as the female parent, and variety 'Yorichard' (Richard) as the male parent. The resultant seed was sown in a greenhouse in October 2007. 'CIDZ0033' was selected as a single plant from the progeny in March 2008 by the breeder, Wendy R. Bergman, based on its flower colour, and plant growth habit.

Tests & Trials: The trial for 'CIDZ0033' 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 and reference varieties on November 14, 2012. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
