The new variety was selected based on its foliage and stripe colouration. Asexual reproduction of ‘Hakbri2' was first conducted by tissue culture in Elma, Washington, USA in early 2022.
Tests & Trials: The comparative trial for ‘Hakbri2' was conducted in an outdoor container trial during the summer of 2023 at BioFlora, Inc. in St. Thomas, Ontario. The trial included 10 plants each of the candidate and reference varieties. Rooted cuttings were transplanted into 3.8 litre containers on April 19, 2024. Observations and measurements were taken from 10 plants, or parts of plants, of each variety on August 16, 2024. All colour determinations were made using the 2015 Royal Horticultural Society (RHS) Colour Chart.
