Origin & Breeding History: 'KLEOE19400' originated from a controlled cross conducted between the female parent designated 'OE-2013-0095' and the male parent designated 'OE-2011-0305' in August 2015 in Nairobi, Kenya. The resulting seed was sown in Stuttgart, Germany. From the resulting progeny, seedlings were selected in May 2016 based on plant growth habit and flower colour in Stuttgart, Germany. All seedlings were since evaluated in greenhouse trials to assess performance.

Tests & Trials: The comparative trial of 'KLEOE19400' was conducted in a polyhouse during the spring of 2023 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 and transplanted into 15 cm pots on May 5, 2023. Observations and measurements were taken from 10 plants, or 10 parts of plants, of each variety on June 22, 2023. All colour determinations were made using the 2015 Royal Horticultural Society (RHS) Colour Chart.
