In September 2008, initial selections of 'Sound of My Heart' were made based on its plant growth habit, foliage and flower type. In the fall of 2009, the new seedling of 'Sound of My Heart' was divided at Walters Gardens, Inc. in Zeeland, Michigan, USA.

Tests & Trials: The comparative trial of 'Sound of My Heart' was conducted outdoors during the summer of 2023 in Oxford Station, Ontario. The trial included a total of 15 plants each of the candidate and reference variety individually grown in 16 cm pots spaced 40 cm apart. Observations and measurements were taken from 10 plants, or parts of plants, of each variety in July 2023. All colour determinations were made using the 2015 Royal Horticultural Society (RHS) Colour Chart. Mean differences were significant at the 5% confidence probability level based on a paired Student's t-test.
