Origin & Breeding History: 'NanSid3' originated from a naturally occurring mutation of the variety Nandina domestica 'Gulfstream', discovered in a block of container grown plants in Mission, British Columbia, in the spring of 2010. The new variety was selected based on the dark red purple colour of its new leaves in the spring. 'NanSid3' was evaluated in greenhouse trials from 2011 to 2015 where it was assessed for uniformity, stability and overall performance. Asexual reproduction of 'NanSid3' was first conducted by tissue culture from stem cuttings in the spring of 2011, in Mission, British Columbia.

Tests & Trials: The comparative trial for 'NanSid3' was conducted in an outdoor container trial during the spring and summer of 2016, at Bioflora Inc., in St. Thomas, Ontario. The trial included a total of 10 shrubs each of the candidate and reference varieties. All shrubs were grown from cuttings that were rooted in the spring of 2014 and transplanted into 3.78 litre containers in the spring of 2015. The trial was arranged outdoors in rows with 1 meter spacing between plants. Spring colours were observed on April 12, 2016 with most observations and measurements recorded on June 22, 2016. Fall colours were observed on November 5, 2016. Observations and measurements were taken from 10 plants or parts of plants from the trial. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
