Origin & Breeding History: 'HOOGI021' originated from an open pollinated cross conducted by the breeder in Ederveen, the Netherlands in 2008. The cross was made between the female parent variety 'Monlo' and pollen from an unknown male parent. The resulting seed from the cross was collected and sown in 2009. The new variety was selected in 2012 as a single unique plant from 350 seedlings based on its growth habit, leaf size and leaf colour. Asexual reproduction of 'HOOGI021' was first conducted by stem cuttings in 2012 in Ederveen, the Netherlands.

Tests & Trials: The comparative trial for 'HOOGI021' was conducted as an outdoor container trial during the summer of 2022 at Bioflora Inc., in St. Thomas, Ontario. The trial included a total of 10 shrubs of the candidate variety and 5 shrubs of the reference variety. All shrubs were grown from rooted cuttings and transplanted into containers in July of 2021. Containers were arranged outdoors in rows with 1 meter spacing between plants. Observations and measurements were taken from 10 plants or parts of 10 plants of each variety on July 15, 2022 with the exception of flower characteristics which were assessed on May 18, 2022. All colour determinations were made using the 2015 Royal Horticultural Society (RHS) Colour Chart. Mean differences were significant at the 5% confidence probability level based on a paired Student's t-test.
