Variety Description

Varieties used for comparison: 'Yohelga' (Helga Cream) and 'PPD PAD WH05' (Padre White)

Summary: The plants of 'CIFZ0007' are taller than the plants of 'PPD PAD WH05'. The leaves of 'CIFZ0007' are shorter than the leaves of 'Yohelga', and narrower than the leaves of both 'PPD PAD WH05' and 'Yohelga'. The length of the terminal lobe of the leaf relative to the leaf length of 'CIFZ0007' is medium while it is long for 'Yohelga'. The depth of indentations of the margin of the leaf is medium depth for 'CIFZ0007' while it is deep for 'Yohelga'. While the flower heads of 'CIFZ0007' and 'PPD PAD WH05' are both double, 'PPD PAD WH05' has a disc which is visible with age whereas 'CIFZ0007' does not. 'CIFZ0007' has a smaller flower head diameter and a shorter ray floret than 'Yohelga'. The colour of the outer side of a ray floret from the inner row of 'CIFZ0007' is white developing pink tones with age whereas for 'Yohelga' it is yellow green, and for 'PPD PAD WH05', the outer side of a ray floret from the inner row is light yellow developing pink tones with age.


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 length to width ratio, length of terminal lobe relative to leaf length is medium, lowest lateral sinus is medium depth, margins of lowest lateral sinus are mostly diverging, predominant shape of base is obtuse and asymmetric, medium green on upper side, few to medium number of indentations of margin, medium depth of indentations of margin

FLOWER BUD: outer side is light yellow (RHS 10D) just before opening
FLOWER HEAD: double, low height in non-disbudded plants, dense ray florets
RAY FLORET: ligulate type, two keels on upper surface, short corolla tube, weakly convex in cross-section at widest point, no rolling of margins, longitudinal axis is straight, longitudinal axis of ray floret from inner row is weakly incurved along distal quarter, low length to width ratio, dentate tip, inner side is white (RHS NN155D) with yellowish white (RHS NN155A) tip, colour of outer side is similar to colour of inner side, outer side is white (RHS NN155D), in comparison to ray floret from inner row the colour of inner and outer sides are similar, outer side of ray floret from inner row is white (RHS NN155A) developing pink tones with age

Origin & Breeding History: 'CIFZ0007' originated from a naturally occurring whole plant mutation from a proprietary line designated '05-M162A'. It was discovered and selected in November 2009 by the breeder, Mark A. Smith, in Alva, Florida, USA. Selection of 'CIFZ0007' was based on its flower colour, and plant growth habit.

Tests & Trials: The trial for 'CIFZ0007' was conducted as an outdoor irrigated trial during the summer of 2012 at BioFlora Inc. in St. Thomas, Ontario. It included a total of 15 plants of the candidate variety and 12 plants each of the reference varieties. All plants were grown from rooted cuttings and transplanted into 20 cm pots on June 11, 2012. Observations and measurements were taken from 10 plants, or parts of plants, of the candidate and reference varieties on September 28, 2012. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
