Origin & Breeding History: 'IBSZ0001' was developed as part of a controlled breeding program by the breeder Henricus Godefridus Wilhelmus Stemkens in Enkhuizen, Netherlands. It originated from a hybrid cross conducted in April 2007 between proprietary lines 'K1007-1' as the female parent, and 'K1077-1' 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 named 'IBSZ0001'.
Tests & Trials: The comparative trial of 'IBSZ0001' was conducted in a polyhouse during the winter and spring of 2014 at BioFlora Inc. in St. Thomas, Ontario. The trial included a total of 20 plants each of the candidate and 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 28, 2014 except for the leaf blade measurements which were taken on April 24, 2014. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
