Origin & Breeding History: 'CIFZ0024' originated from a naturally occurring whole plant mutation of a proprietary, unnamed sport of the variety 'Jacqueline'. It was discovered and selected on March 9, 2009 by the breeder, Mark A. Smith, in Alva, Florida, USA. Selection of 'CIFZ0024' was based on its plant growth habit, natural season response time, and flower size and type.

Tests & Trials: The trial for 'CIFZ0024' was conducted as an outdoor irrigated trial during the summer of 2012 at BioFlora Inc. in St. Thomas, Ontario. It included a total of 20 plants of the candidate variety and 12 plants of the reference variety. 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 24, 2012. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
