Origin & Breeding History: 'INOSTBLPUR' originated from a controlled cross conducted by Silvia Hofmann, an employee of InnovaPlant Zierpflanzen GmbH & Co. KG in Gensingen, Germany in July 2014. The cross was made between proprietary seedlings designated 'O 13 201-1', as the female parent, and 'O 13 24-1', as the male parent. From the resulting progeny, the new variety was selected in April 2015 as a single plant based on its flower colour, flower quality and heat tolerance. 'INOSTBLPUR' was first propagated by vegetative cuttings in June 2015 in Gensingen, Germany.

Tests & Trials: The comparative trial for 'INOSTBLPUR' was conducted in a polyhouse at BioFlora in St. Thomas, Ontario during the spring of 2021. The trial included 20 plants each of the candidate and reference varieties. All plants were grown from rooted cuttings and transplanted into 15 cm pots on April 16, 2021. Observations and measurements were taken from 10 plants, or parts of plants, of each variety on June 4, 2021. All colour determinations were made using the 2015 Royal Horticultural Society (RHS) Colour Chart.
