Origin & Breeding History: 'INTA 06575' originated from a controlled cross conducted by the breeders, Juan Carlos Hagiwara, Maria Julia Pannunzio and Facciuto Gabriela Rosa employees of the Instituto Nacional de Tecnologia Agropecuaria, Argentina. The cross was made between the female parent Calibrachoa caesia designated '20030925I2' and the male parent Calibrachoa hybrida designated 'Dark Blue', in September 2005 in Hurlingham, Beunos Aires, Argentina. From the resulting progeny, 'INTA 06575' was selected as a single plant in October 2006 based on its growth habit, freely branching nature, free flowering, flower colour and good summer and garden performance. Asexual reproduction of 'INTA 06575' was first conducted by vegetative cuttings in October 2016 in Hurlingham, Beunos Aires, Argentina.

Tests & Trials: The comparative trial for 'INTA 06575' was conducted in a polyhouse during the spring of 2016 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 30 cm hanging baskets on April 20, 2016. Each basket contained 4 cuttings with a total of 5 baskets per variety. Observations and measurements were taken from 10 plants, or parts of plants, of each variety on June 13, 2016. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
