Origin & Breeding History: 'SMNJRPU' originated as an open pollinated cross and was bred and developed by the breeder, Timothy D. Wood, an employee of Spring Meadow Nursery, Inc. in Grand Haven, Michigan, USA. The open pollinated cross occurred between the proprietary female parent 'JosRebloom' and pollen from an unnknown male parent in Grand Haven, Michigan, USA in 2010. 'SMNJRPU' was selected in 2013 based on its flower colour and reblooming tendency. 'SMNJRPU' was first asexually propagated by softwood cuttings in June 2013 in Grand Haven, Michigan, USA.

Tests & Trials: The comparative trial for 'SMNJRPU' was conducted in a polyhouse during the spring of 2021 at BioFlora Inc. in St. Thomas, Ontario. The trial included a total of 10 shrubs each of the candidate and reference variety. Rooted cuttings were transplanted into 8.8 litre containers on August 7, 2019. Observations and measurements were taken from 10 plants, or parts of 10 plants, of each variety on May 11, 2021. All colour determinations were made using the 2015 Royal Horticultural Society (RHS) Colour Chart.
