Origin & Breeding History: 'KLEVP11419' was bred and developed by the breeder, Ruijun Li, an employee of NuFlora International Pty, Ltd. at the University of Sydney, Cobbitty in Camden, New South Wales, Australia. It originated from a controlled cross pollination conducted in April 2008 between the proprietary varieties '1 S 109' as the female parent and 'V 842' as the male parent. In January 2009, in Cobbitty, seedlings obtained from this cross were selected based on their flower quality and further evaluated from January to May 2009 in greenhouse trials to assess flower quality. In May 2011, in Stuttgart, Germany, 'KLEVP11419' was selected for commercialization.

Tests & Trials: The comparative trial of 'KLEVP11419' was conducted in a polyhouse during the spring of 2014 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 which were transplanted into 15.2 cm shallow pots on April 23, 2014. Observations and measurements were taken from 10 plants or parts of plants of each variety on June 3, 2014. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
