The new variety was developed by the breeder, Ushio Sakazaki, in Higashiomi, Shiga, Japan. 'USCAL69404' was selected as a single seedling from the resultant progeny on June 9, 2015 in Bonsall, California, USA based on plant vigour, plant branching; flower colour and pattern. The new variety 'USCAL69404' was first propagated by vegetative tip cuttings on June 10, 2015, in Bonsall, California, USA.

Tests & Trials: The comparative trial for 'USCAL69404' was conducted in a polyhouse during the summer of 2018 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 and transplanted into 30 cm hanging baskets on May 6, 2018. Each basket contained 4 cuttings with a total of 5 baskets per variety. Observations and measurements were taken from 10 plants, or parts of plants, of each variety on June 18, 2018. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
