Origin & Breeding History: 'KERBESPICUP' originated as a branch mutation discovered by the breeders in June of 2016 in Cambridge, United Kingdom. The branch mutation was discovered on the parent variety 'Kerbespicit' and selected based on its growth habit, flower colour and flower fragrance. 'KERBESPICUP' was first propagated by vegetative tip cuttings in June of 2016 in Cambridge, United Kingdom.

Tests & Trials: The comparative trial for 'KERBESPICUP' was conducted in a polyhouse during the spring of 2022 at Bioflora Inc., in St. Thomas, Ontario. The trial included a total of 20 plants each of the candidate and reference varieties. All plants were grown from rooted cuttings and transplanted into 15 cm pots on April 7, 2022. Observations and measurements were taken from 10 plants, or parts of 10 plants, of each variety on July 1, 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.
