Origin & Breeding History: 'SMNPPS' originated from an open pollinated cross conducted by the breeder, Timothy D. Wood, in Grand Haven, Michigan, USA. The cross was made between the female parent variety designated 'Pink Dbl 2 F2', and an unknown male parent in 2011. The new variety was selected as a single plant from the resulting progeny in 2014, based on plant growth habit and flower colour. Asexual reproduction of 'SMNPPS' was first conducted by softwood cuttings in the summer of 2014, in Grand Haven, Michigan, USA.
Tests & Trials: The comparative trial for 'SMNPPS' was conducted in containers outdoors during the summer of 2020 at Bioflora Inc., in St. Thomas, Ontario. The trial included a total of 10 shrubs each of the candidate variety and reference variety. All shrubs were grown from rooted cuttings and transplanted into 11.3 litre pots on August 6, 2019. The trial was arranged outdoors in rows with 1 metre spacing between plants. Observations and measurements were taken from 10 plants, or parts of 10 plants of each variety on July 21, 2020. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
