Origin & Breeding History: 'Winsusnobl' originated from a controlled cross conducted by the breeder, Mr. Benjamin Kent Winslow, in Alejuela, Costa Rica. The cross was made between the female parent variety 'Scopia Gulliver Blue' and the male parent variety 'MegaCopa Blue' in November 2016. The new variety was selected as a single plant from the resulting progeny on November 1, 2017, in Carleton, Michigan, USA, based on its growth habit, branching characteristics, flower size, flower colour and heat tolerance. Asexual reproduction of 'Winsusnobl' was first conducted by tissue culture on December 11, 2017 in Zeeland, Michigan, USA.
Tests & Trials: The comparative trial for 'Winsusnobl' was conducted in a polyhouse during the spring of 2020 at Bioflora Inc., in St. Thomas, Ontario. The trial included a total of 20 plants each of the candidate variety and reference variety. All plants were grown from rooted cuttings and transplanted into 15 cm pots on April 16, 2020. Observations and measurements were taken from 10 plants of each variety on May 22, 2020. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
