Origin & Breeding History: 'SAXZ0008' was developed as part of a controlled breeding program by the breeder, Henricus Godefridus Wilhelmus Stemkens, in Enkhuizen, Netherlands. It originated from a cross conducted in April 2007 between proprietary lines 'J1627-51' as the female parent and 'K0630-1' as the male parent. The resultant seed was sown in a greenhouse in August 2007. In March 2008, a single plant from the progeny was selected for its flower colour and plant growth habit and later named 'SAXZ0008'.
Tests & Trials: The comparative trial of 'SAXZ0008' was conducted in a polyhouse during the spring of 2014 at BioFlora Inc. in St. Thomas, Ontario. The trial included 20 plants of the candidate and reference variety. All plants were grown from rooted cuttings and transplanted into 11.4 cm pots on August 15, 2013. Observations and measurements were taken from 10 plants or parts of plants of the candidate and reference varieties on February 28, 2014. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
