Origin & Breeding History: 'LAAZ0001' was bred and developed by the breeder, Henricus G.W. Stemkens, as part of a planned breeding program of Syngenta Seeds B.V. in Enkhuizen, Netherlands. It originated from a cross conducted in August 2005 between a proprietary line designated 'G3012-13' as the female parent, and an unknown male parent. The resultant seed was collected and sown in a greenhouse in Enkhuizen during the spring of 2006. 'LAAZ0001' was selected in July 2006 based on its flower colour and plant growth habit.

Tests & Trials: The trial of 'LAAZ0001' was conducted in a polyhouse during the fall of 2013 at BioFlora Inc. in St. Thomas, Ontario. It included 20 plants each of the candidate and reference variety. Rooted cuttings were planted into 15 cm pots on August 14, 2013. Observations and measurements were taken from 10 plants or parts of plants of each variety on September 26, 2013. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
