Origin & Breeding History: 'CIFZ0030' originated from a controlled cross-pollination conducted in December 2007, in Amanecer, Columbia, as part of a controlled breeding program of Syngenta Flowers, Inc. The cross involved variety 'Yoelena' (Elena Gold) as the female parent, and variety 'Yodiana' (Diana) as the male parent. The resultant seed was sown in a greenhouse in Alva, Florida, USA, in June 2008. 'CIFZ0030' was selected as a single plant from the progeny on October 24, 2008 by the breeder, Mark A. Smith, based on its natural season response time, flower size and type, plant growth habit, and strength.

Tests & Trials: The trial for 'CIFZ0030' 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.
