The new variety ‘WNCALSBDBLRS24' was selected on August 26, 2019 based on plant vigour, branching density, double type flowers, flower colour, time of flowering and frequency of flowering. Asexual reproduction by cuttings was initiated in Bonsall, California, USA on August 26, 2019.

Tests & Trials: The comparative trial for ‘WNCALSBDBLRS24' was conducted in a polyhouse during the summer of 2025 at Bioflora Inc., 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 30 cm hanging baskets on April 14, 2025. 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 May 28, 2025. 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.
