The plants were selected in 2007 for their colour and growth habit for general garden and landscape use.
Tests & Trials: The comparative trial for 'Blueberry Sundae' was conducted in an open ended polyhouse during the spring of 2014 at Variety Rights Management in Oxford Station, Ontario. The plants were grown in 23 cm round pots, one plant per pot with 45 cm spacing between the pots. Observations and measurements were taken from 14 plants of each variety. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
