Origin & Breeding History: 'SUTZ0001' was developed by the breeder, Erwin de Jong, in Enkhuizen, Netherlands, as part of a controlled breeding program of Syngenta Crop Protection AG, Switzerland. It originated from a cross conducted during the summer of 2008 between a proprietary line designated 'L0001-1' as the female parent and a proprietary line designated 'K0006-4' as the male parent. The resultant seed was sown in a greenhouse in the spring of 2009. In late spring of 2009, 'SUTZ0001' was selected by the breeder based on its flower colour and plant growth habit.

Tests & Trials: The trial for 'SUTZ0001' was conducted in a polyhouse during the spring of 2013 at BioFlora Inc. in St. Thomas, Ontario. It included a total of 20 plants each of the candidate and reference variety. All plants were grown from rooted cuttings and transplanted into 15 cm pots on April 16, 2013. Observations and measurements were taken from 10 plants or parts of plants of each variety on May 30, 2013. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
