Origin & Breeding History: 'CIFZ0031' originated from a controlled cross-pollination conducted in December 2006, in Amanecer, Columbia, as part of a controlled breeding program of Syngenta Flowers, Inc. The cross involved variety 'Yoashley' (Ashley Dark Orange) as the female parent, and a line designated '04-M1732' as the male parent. The resultant seed was sown in a greenhouse in Alva, Florida, USA, in June 2007. 'CIFZ0031' was selected as a single plant from the progeny on November 15, 2007 by the breeder, Mark A. Smith, based on its natural season response time, flower size and type, and plant growth habit.

Tests & Trials: The trial for 'CIFZ0031' 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 October 1, 2012. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
