Origin & Breeding History: 'Inheubrara' originated from an open pollinated cross conducted by the breeder, Mr. Walter Ludwig, in Heidesheim, Germany. The cross was made between the variety 'Fire Chief' as the female parent and an unknown male parent. From the resultant progeny, 'Inheubrara' was selected based on its leaf colour and flower colour in March 2010 in Heidesheim, Germany. 'Inheubrara' was first asexually propagated by plant division in April 2010 in Gensingen, Germany.

Tests & Trials: The comparative trial for 'Inheubrara' was conducted in a polyhouse during the spring of 2015 at BioFlora Inc. in St, Thomas, Ontario. The trial included a total of 20 plants each of the candidate and reference variety. Rooted cuttings were transplanted into 15 cm pots on May 11, 2015. Observations and measurements were taken from 10 plants or parts of plants of each variety on June 8, 2015. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
