Origin & Breeding History: 'Isopapi' originated from a controlled cross conducted by Elke Steffen, an employee of Elsner pac Jungplanzen GbR, in the summer of 2012 in Dresden, Germany. Both parents are unnamed proprietary breeding lines that were part of a bulked group of breeding clones. 'Isopapi' was selected in the summer of 2013 in Dresden, Germany for its branching, flower colour and flower characteristics. 'Isopapi' was initially asexually propagated through vegetative cuttings in the summer of 2013 in Dresden, Germany.
Tests & Trials: The comparative trial for 'Isopapi' was conducted in a polyhouse during the summer of 2021 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 3.8 litre round pots on April 22, 2021. The observations and measurements were taken from 10 plants, or 10 parts of plants, of each variety on June 24, 2021. All colour determinations were made using the 2015 Royal Horticultural Society (RHS) Colour Chart.
