Origin & Breeding History: 'INCALCOBLU' originated from a controlled cross conducted by the breeder, Birgit Hofmann, an employee of InnovaPlant Zierpflanzen GmbH & Co. KG, Gensingen, Germany. The cross was made in November 2015 in Johannesburg, South Africa between the female parent variety 'Calipetite Blue' and the proprietary male seedling designated 'Ca14-5432-2'. From the resulting progeny, 'INCALCOBLU' was selected as a single plant in April 2017 based on its plant growth habit, early flowering and flower colour. The first propagation by vegetative tip cuttings of 'INCALCOBLU' took place in April 2017 in Heidesheim, Germany.

Tests & Trials: The comparative trial for 'INCALCOBLU' was conducted in a polyhouse during the summer of 2020 at BioFlora Inc. in St. Thomas, Ontario. There were 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 May 21, 2020. Observations and measurements were taken from 10 plants, or parts of plants, on June 8, 2020. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
