Origin & Breeding History: 'SMNSRD4' 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 that was conducted in May 2006, between Sambucus racemosa variety 'Dropmore Fernleaf', as the female parent, and Sambucus racemosa variety 'Sutherland Gold' as the male parent. 'SMNSRD4' was selected in May 2011, for its compact growth habit, bright yellow foliage with high resistance to sunburn, and fine-cut foliage. Asexual reproduction of 'SMNSRD4' was first conducted by softwood cuttings in Grand Haven, Michigan, USA.
Tests & Trials: The comparative trial for 'SMNSRD4' was conducted as an outdoor irrigated container trial during the summer of 2016, at Bioflora Inc., in St. Thomas, Ontario. The trial included a total of 12 shrubs each of the candidate and reference variety. All shrubs were grown from rooted cuttings and transplanted into 8.8 litre containers on July 13, 2015. The containers were arranged outdoors in rows, with 1 metre spacing between plants. The observations and measurements were taken from 10 plants, or plant parts, of each variety on July 27, 2016. The flower observations were made on May 12, 2016. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
