Description:

PLANT: garden chrysanthemum, bushy type, hemispherical growth habit, dense branching, many flower heads
STEM: green

PETIOLE: attitude is moderately upwards, medium length relative to leaf length
LEAF: medium to high length to width ratio, length of terminal lobe relative to leaf length is medium, lowest lateral sinus is shallw to medium depth, margins of lowest lateral sinus are diverging, predominant shape of base is obtuse, absent or very weak glossiness of upper side, dark green on upper side, few indentations of margin, medium depth of indentations of margin

FLOWER BUD: white (closest to RHS 155A) just before opening
FLOWER HEAD: double type, medium to dense ray florets
RAY FLORET: predominant type is ligulate, secondary type is spatulate and very few, two keels on upper surface, medium length corolla tube, mostly flat with some being weakly convex and weakly concave in cross section at widest point, no rolling of margins, longitudinal axis is mostly straight with some being weakly reflexed along distal half, medium length to width ratio, rounded tip, inner side is white (RHS NN155A-B), colour of outer side is similar to colour of inner side, in comparison to ray floret from inner row the colours of the inner and outer sides are markedly different, both the inner and outer sides of ray floret from inner row are light yellow (whiter than RHS 4D)

Origin & Breeding History: 'CIFZ0023' was bred and developed as part of a controlled breeding program at Syngenta Flowers Inc., in Gilroy, California, USA. It originated from a cross conducted in January 2008 by the breeder, Mark A. Smith, in Amanecer, Columbia, USA, between the variety 'Yoalexis' as the female parent, and the proprietary line designated '03-M342' as the male parent. The resultant seed was sown in a greenhouse in June 2009, in Alva, Florida, USA. 'CIFZ0023' was selected in November 2009 based on its flower colour and plant growth habit. The first propagation of 'CIFZ0023' using asexual reproduction occurred in January 2010, in Alva, Florida, USA.

Tests & Trials: The trial of 'CIFZ0023' was conducted as an outdoor irrigated trial during the fall of 2013 at BioFlora Inc. in St. Thomas, Ontario. It included a total of 20 plants of the candidate variety and 15 plants of the reference variety. All plants were grown from rooted cuttings and transplanted into 20 cm chrysanthemum pans on June 25, 2013. Observations and measurements were taken from 10 plants, or parts of plants, of the candidate and reference varieties on September 19, 2013. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
