Origin & Breeding History: 'SMNBDL' originated from a controlled hybrid cross conducted by the breeder, Mr. Timothy D. Wood, in Grand Haven, Michigan, USA. The cross was made between the female parent, designated 'UC 701', and the male parent variety 'Pink Delight' in 2012. The new variety was selected as a single plant from the resulting progeny in 2014, based on its growth habit, stem thickness, stem internode length, leaf appearance, leaf texture, panicle size, panicle density and flower colour. Asexual reproduction of 'SMNBDL' was first conducted by softwood cuttings in 2014, in Grand Haven, Michigan, USA.
Tests & Trials: The comparative trial for 'SMNBDL' was conducted in a polyhouse during the spring and summer of 2020 at Bioflora Inc., in St. Thomas, Ontario. The trial included a total of 10 plants each of the candidate variety and reference varieties. All plants were grown from 5.7 cm rooted liners and transplanted into 11.3 litre containers on April 6, 2019. Observations and measurements were taken from 10 plants of each variety on June 26, 2020. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
