Origin & Breeding History: 'PEZZ0002' originated from a controlled cross conducted in October 2007, in Gilroy, California, USA between the female parent, a proprietary line identified as 209-2, and the male parent, a proprietary line identified as 209-3. 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 May 2008. In September 2008, the new Pentas variety 'PEZZ0002' was selected as a single plant from the progeny based on flower colour and plant habit.

Tests & Trials: Trials for 'PEZZ0002' were conducted in a polyhouse during the spring of 2013 in St. Thomas, Ontario. The trial included 21 plants of the candidate variety and 11 plants of the reference variety. All plants were grown from rooted cuttings and transplanted into 8 cm pots in late July 2013. Observations and measurements were taken from 10 plants of each variety on September 19, 2013. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
