Origin & Breeding History: 'KLEVP12446' was bred and developed by the breeder, Ruiujn 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 2007 between the proprietary varieties 'F 2' as the female parent and 'V 842' as the male parent. In January 2008, in Cobbitty, seedlings obtained from this cross were selected based on their flower colour, plant growth habit, and tolerance to powdery mildew, and then further evaluated from January to May 2008 in greenhouse trials to assess flowering time and flower colour. In August 2010, in Stuttgart, Germany, 'KLEVP12446' was selected for commercialization.

Tests & Trials: The comparative trial of 'KLEVP12446' 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 4, 2014. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
