Origin & Breeding History: 'KLEDH11031' was bred and developed by the breeder, Andrea Dohm, in Stuttgart, Germany. It originated from a hybrid cross conducted in September 2007, in Stuttgart, between a proprietary variety designated 'DH 2006 0095', as the female parent, and a proprietary variety designated 'DH 2006 0039', as the male parent. From the resulting progeny, seedlings were selected for flower colour, flower shape, branching characteristics and mildew resistance. These selected seedlings were evaluated in greenhouse trials from February to May 2009, 2010, 2011, and 2012, in Stuttgart, Germany, during which they were further assessed for early flowering, plant vigour, good branching and mildew resistance. 'KLEDH11031' was selected in August 2010, in Stuttgart, Germany, for commercialization.

Tests & Trials: The comparative trial of 'KLEDH11031' was conducted in a polyhouse during the spring of 2015 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 that were each transplanted into a 15 cm pot on April 15, 2015. Observations and measurements were taken from 10 plants or parts of plants of the candidate variety on May 21, 2015, and from 10 plants or parts of plants of the reference variety on June 5, 2015. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
