Origin & Breeding History: 'KLEPH20490' originated from a controlled cross conducted in July 2016 in Latina, Italy between the proprietary seedling designated 'PH-2014-0777' as the female parent, and the proprietary variety designated 'PH-2015-1208' as the male parent. 'KLEPH20490' was selected in April 2017 in Latina based on plant growth habit, leaf quality and flower quality and colour.

Tests & Trials: The comparative trial for 'KLEPH20490' was conducted in a polyhouse during the spring of 2023 in St. Thomas, Ontario. The trial included 20 plants each of the candidate and reference varieties. All plants were grown from rooted cuttings and transplanted into 15.2 cm pots on April 19, 2023. Observations and measurements were taken from 10 plants, or 10 parts of plants on June 6, 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.
