The initial selection was made in March 2009, one plant was selected for its floriferousness, deep black coloured flowers, medium green coloured foliage and outwardly spreading mounded growth habit. It has been further propagated through vegetative cuttings.

Tests & Trials: Trials for 'Blackout' were conducted in a polyhouse during the spring of 2013 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 11.5 cm pots on April 16, 2013. Observations and measurements were taken from 10 plants of each variety on May 22, 2013. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
