Origin & Breeding History: 'RNI-RCC3' originated from an open pollinated cross between two unknown parents conducted in the summer of 2015 in Wisconsin, USA. The new variety 'RNI-RCC3' was selected in McMinnville, Oregon, USA on May 5, 2017 based on plant habit, plant vigour and foliage colour. Asexual reproduction by budding was initiated in McMinnville in August of 2018.

Tests & Trials: The comparative trial for 'RNI-RCC3' was conducted in a polyhouse during the spring/summer of 2023 in St. Thomas, Ontario. The trial included a total of 10 plants each of the candidate and reference variety. All plants were grown from rooted cuttings, transplanted into 11 litre containers in the spring of 2023. Observations and measurements were taken from 10 plants or parts of 10 plants of each variety on August 18, 2023. Mean differences were significant at the 5% confidence probability level based on a paired Student's t-test. All colour determinations were made using the 2015 Royal Horticultural Society (RHS) Colour Chart.
