Origin & Breeding History: 'Pink Dawn' originated as a chance seedling found in the summer of 2012 in Zeeland, Michigan, USA in a garden near a planting of Salvia variety 'May Night'. The plant appeared to have some Salvia pretense in its parentage but exact parents are unkown. 'Pink Dawn' was selected in the fall of 2012 for its intense pink floral display on compact plants.

Tests & Trials: The comparative trial for 'Pink Dawn' was conducted during the summer of 2016 at Variety Rights Management in Oxford Station, Ontario. The trial included a total of 15 plants of the candidate variety and 12 plants of the reference variety. All plants were grown in 16 cm pots spaced 45 cm apart. Observations and measurements were taken from 10 plants, or parts of plants, of each variety on June 4, 2016. All colour determinations were made using the 2015 Royal Horticultural Society (RHS) Colour Chart.
