Origin & Breeding History: ‘INHELAROPU' originated from a controlled cross conducted in the summer of 2012 in Heidesheim, Germany, between the female parent ‘Incense' and the male proprietary parent ‘H10-1001-10'. ‘INHELAROPU' was selected as a unique single flowering plant in the spring of 2013 based on branching, time of flowering, and cold tolerance. Asexual reproduction of ‘INHELAROPU' was conducted by vegetative cuttings in June 2013 in Heidesheim, Germany.

Tests & Trials: The comparative trial for ‘INHELAROPU' was conducted in a polyhouse during the summer of 2025 at BioFlora Inc. in St. Thomas, Ontario. The trial included a total of 20 plants each of the candidate and reference variety. All plants were grown from rooted cuttings and transplanted into 11 cm pots on April 7, 2025. Observations and measurements were taken from 10 plants, or parts of plants, of each variety on May 27, 2025. All colour determinations were made using the 2015 Royal Horticultural Society (RHS) Colour Chart. Mean differences were significant at the 5% probability level based on a Student's t-test.
