Origin & Breeding History: 'WNCYLASUN' originated from a controlled cross conducted by the breeder Brent D. Barnes on April 25, 2017 in Bonsall, California, USA. The cross was made between two proprietary seedlings designated as '17TX073-02' (female parent variety) and '16CLPS01-01' (male parent variety). From the resulting progeny, a single plant was selected on September 13, 2018 in Bonsall, California, USA based on plant growth habit, flower size, flower abundance and length of flowering period. 'WNCYLASUN' was initially asexually propagated by cuttings on September 18, 2018 in Bonsall, California, USA.
Tests & Trials: The comparative trial for 'WNCYLASUN' was conducted in a polyhouse during the spring of 2022 at BioFlora, Inc. in St. Thomas, Ontario. The trial included a total of 15 plants each of the candidate and reference variety. All plants were grown from rooted cuttings and transplanted into 15 cm pots on April 5, 2022. Observations and measurements were taken from 10 plants, or parts of plants, of each variety on June 9, 2022. All colour determinations were made using the 2015 Royal Horticultural Society (RHS) Colour Chart.
