Origin & Breeding History: 'KLECA22491' originated from a controlled cross conducted in May 2016 in Stuttgart, Germany between the proprietary seedling designated 'CA-2009-1427' as the female parent, and the proprietary variety designated 'CA-2014-4088' as the male parent. 'KLECA22491' was selected in May 2016 in Stuttgart, Germany based on plant growth habit, branching, flower size and appearance, and time of flowering. After evaluations in greenhouse for the above criteria and overall performance, the new variety 'KLECA22491' was selected for commercialization in May 2020.

Tests & Trials: The comparative trial for 'KLECA22491' was conducted in a polyhouse during the summer of 2023 in St. Thomas, Ontario. The trial included 20 plants each of the candidate and reference variety. All plants were grown from rooted cuttings and transplanted into 30 cm hanging baskets on April 29, 2023. Each basket contained 4 cuttings with a total of 5 baskets per variety. Observations and measurements were taken from 10 plants, or 10 parts of plants, on June 7, 2023. Mean differences were significant at the 5% confidence probability level based on a paired Student's t-test. All colour determinations were made using the 2015 Royal Horticultural Society (RHS) Colour Chart.
