Origin & Breeding History: 'Gaulsidh11' originated from an open pollinated cross that occurred in 2006, in Mission, British Columbia, in a greenhouse production bed of Gaultheria procumbens seedlings. The new variety was discovered as a chance seedling in the fall of 2010 and was selected based on its growth habit, leaf shape, berry set and berry distribution along the stems. 'Gaulsidh11' was evaluated in greenhouse trials from 2011 to 2015 and assessed for stability, uniformity and overall performance. Asexual reproduction of 'Gaulsidh11' was first conducted by tissue culture from stem cuttings in April 2011, in Mission, British Columbia.
Tests & Trials: The comparative trial for 'Gaulsidh11' was conducted in late 2015 and throughout the spring to fall of 2016, at Bioflora Inc., in St. Thomas, Ontario. The trial included a total of 10 plants of the candidate variety and 8 plants of the reference variety. All plants were grown from young plants in 10 cm diameter pots and transplanted to 12 cm deep containers on November 5, 2015. The plants were over-wintered in a double polyhouse and moved outdoor in the spring of 2016 to an irrigated trial area. Observations and measurements of fruit and winter leaf colours where taken on December 27, 2015, leaf and flower characteristics were taken on August 10, 2016, fall foliage colours were taken on November 11, 2016. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
