Origin & Breeding History: 'ABRZ0002' originated from a controlled cross between the female parent designated 'G1424-52' and the male parent designated 'E0580-1' made in April 2007 by the breeder H. Stemkens, an employee of Syngenta Seeds B.V. in Enkhuizen, the Netherlands. The resultant seed was sown in a greenhouse in August 2007. 'ABRZ0002' was selected in March 2008 based on its flower colour and plant growth habit.

Tests & Trials: The comparative trial for 'ABRZ0002' was conducted in a polyhouse during the winter of 2014 at BioFlora Inc., St. Thomas, Ontario. There were 30 plants of the candidate variety and 25 of the reference variety. All plants were grown from rooted cuttings and transplanted into 15.2 cm pots on August 15, 2013. Observations and measurements were taken from 10 plants or parts of plants of each variety on February 13, 2014. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
