Origin & Breeding History: 'WNVESBIB' originated from a controlled cross conducted by Brent D. Barnes on August 31, 2017, in Bonsall, California, USA. The cross was made between the proprietary female parent designated '17V508-01' and the male parent variety 'RIKAV18302' (Superbena Violet Ice). On August 2, 2018, a single plant was selected from the resulting progeny in Bonsall, California based on plant vigour, growth habit, floret and inflorescence size and resistance to powdery mildew. Asexual reproduction of the variety 'WNVESBIB' was first conducted by vegetative cuttings on August 6, 2018, Bonsall, California, USA.

Tests & Trials: The comparative trial for 'WNVESBIB' was conducted in a polyhouse during the summer of 2022, 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 transplanted into 15 cm diameter pots on April 6, 2022. Observations and measurements were taken from 10 plants, or parts of plants, on June 6, 2022. All colour determinations were made using the 2015 Royal Horticultural Society (RHS) Colour Chart.
