Origin & Breeding History: 'WNPETMVSS23' originated from a controlled cross conducted on October 15, 2019 in Bonsall, California, USA between the proprietary seedling designated 'PS001*001' as the female parent, and the proprietary variety designated '17PB276-01' as the male parent. 'WNPETMVSS23' was selected on October 5, 2020 in Tyler, Texas, USA based on plant growth habit, branching density, as well as flower colour, flower size, free flowering and time of flowering. Asexual reproduction of the variety was first conducted by cuttings on October 12, 2020 in Texas, USA.

Tests & Trials: The comparative trial for 'WNPETMVSS23' was conducted in a polyhouse during the spring of 2023 in St. Thomas, Ontario. The trial included 20 plants of each of the candidate and reference varieties. All plants were grown from rooted cuttings and transplanted into 15.2 cm pots on April 13, 2023. Observations and measurements were taken from 10 plants, or 10 parts of plants on May 30, 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.
