This variety was selected in the spring of 2010 based on its strong healthy growth, strong tendency to re-bloom, dark purple bud colour and dark lavender flower colour.

Tests & Trials: The comparative trial for 'SMSJBP7' was conducted in a polyhouse during the spring of 2014 at BioFlora Inc. in St. Thomas, Ontario. The trial included a total of 10 shrubs each of the candidate and reference variety. All plants were grown from quick-turn liners and planted into 8.8 litre containers on June 7, 2013. Observations and measurements were taken from 10 plants of each variety on April 3, 2014, except for flower characteristics which were taken on April 29, 2014. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
