Origin & Breeding History: 'SMNHALR' was bred and developed by the breeder, Timothy D. Wood, an employee of Spring Meadow Nursery, Inc., in Grand Haven, Michigan, USA. It originated from a cross conducted in July 2007 between an unidentified plant of Hydrangea arborescens subsp. radiata, as the female parent, and the Hydrangea arborescens variety 'Pink Pincushion', as the male parent. From the resulting progeny, 'SMNHALR' was selected in July 2011 for its large inflorescences, green sterile flower sepals, and fertile flower colour. 'SMNHALR' was first propagated asexually by soft wood cuttings in July 2011, in Grand Haven, Michigan, USA.

Tests & Trials: The comparative trial for 'SMNHALR' was conducted in an outdoor container trial during the spring and summer of 2016, at BioFlora Inc., in St. Thomas, Ontario. The trial included 12 shrubs each of the candidate and reference variety. All shrubs were grown from rooted cuttings and transplanted into 14 litre containers on July 15, 2015. The plants were overwintered in a cold double polyhouse without heat. The observations and measurements were taken from 10 plants or parts of plants of each variety on June 21, 2016. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
