Origin & Breeding History: 'NanSid11' originated from a naturally occurring mutation of the Nandina domestica variety 'Gulfstream', discovered in a block of container grown plants in Mission, British Columbia, in the spring of 2016. The new variety was selected based on the colour of the new growth. Asexual reproduction of 'NanSid11' was first conducted by tissue culture in the spring of 2017, in Mission, British Columbia.

Tests & Trials: The comparative trial for 'NanSid11' was conducted in an outdoor container trial during the summer of 2021, at Bioflora Inc., in St. Thomas, Ontario. The trial included a total of 10 shrubs each of the candidate and reference variety. All shrubs were grown from cuttings that were rooted in the early spring of 2021. Observations and measurements were taken from 10 plants or parts of plants in the spring and summer of 2021. All colour determinations were made using the 2015 Royal Horticultural Society (RHS) Colour Chart.
