Origin & Breeding History: 'PEZZ0004' originated from a controlled cross conducted in July 2006, in Gilroy, California, USA between the female parent, a proprietary line identified as T5OH-4, and the male parent, a proprietary line identified as T37H-1. The new variety was bred and developed by the breeder Jason Jandrew as part of a controlled breeding program. The resultant seed from the cross was sown in a greenhouse in January 2007. In May 2007, the new Pentas variety 'PEZZ0004' was selected as a single plant from the progeny based on flower colour and plant habit.

Tests & Trials: Trials for 'PEZZ0004' were conducted in a polyhouse during the spring of 2013 in St. Thomas, Ontario. The trial included 20 plants each of the candidate and reference varieties. All plants were grown from rooted cuttings and transplanted into 15 cm pots on April 25, 2013. Observations and measurements were taken from 10 plants of each variety on July 4, 2013. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
