The colour of the stem of 'SMHPZIND' is dark red brown whereas the stem of 'SMHPFL' is brown and the stem of 'Limelight' is light brown green. The leaf blade of 'SMHPZIND' is larger with a longer petiole than the leaf blade of 'SMHPFL'. Plants of 'SMHPZIND' begin to flower mid to late season while the plants of 'SMHPFL' begin to flower mid-season. The inflorescence of 'SMHPZIND' is larger in diameter than 'SMHPFL' and smaller in diameter than the inflorescence of 'Limelight'. The calyx of the sterile flower of 'SMHPZIND' is larger in diameter than the calyx of 'Limelight'. When the sterile flower is newly open, the colour of the inner side of the sepal of 'SMHPZIND' is light green while the inner side of the sepal of 'SMHPFL' is yellow green. When the sterile flower is fully open, the colour of the inner side of the sepal of 'SMHPZIND' is light yellow and white with light green tones around the veins while the inner side of the sepal of 'SMHPFL' is white. When aged, the colour on the inner side of the sepal of a sterile flower from the distal part of the inflorescence of 'SMPHZIND' has tones of purple red with blue pink to light blue pink along the margin and the sepal of an aged sterile flower from the basal part of the inflorescence is purple red with light green at the base whereas the inner side of the sepal of 'SMHPFL' is purple red to purple and the inner side of the sepal of 'Limelight' is light green with purple red tones and darker purple red along margins.

Origin & Breeding History: 'SMHPZIND' was bred and developed by the breeder, Timothy D. Wood, of Spring Meadow Nursery, Inc. in Grand Haven, Michigan, USA. It originated from an open pollinated cross that occurred in July 2007 between the variety 'DVPPinky' as the female parent, and an unknown male parent. 'SMHPZIND' was selected in July 2009 for its strong stems, strong blooming, inflorescence made up of many small, showy sepals, and inflorescences that age to an attractive pink colour. Asexual reproduction of 'SMHPZIND' by softwood cuttings was first conducted in July 2009, in Grand Haven, Michigan, USA.

Tests & Trials: The comparative trial of 'SMHPZIND' was conducted as an outdoor container trial during the summer of 2014 at BioFlora Inc. in St. Thomas, Ontario. It included a total of 12 shrubs each of the candidate and reference varieties. All shrubs were grown from rooted cuttings and transplanted into 11.4 litre containers on June 19, 2013. Observations and measurements were taken from 10 shrubs or parts of shrubs of the candidate variety on August 15, 2014, from the reference variety 'SMHPFL' on July 28, 2014, and from the reference variety 'Limelight' on August 15, 2014. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
