Tests & Trials: Trials were conducted during the summer of 2011 in Oxford Station, Ontario. Ten plants of each variety were grown in 22 cm pots in a polyhouse. Plants were spaced approximately 60 cm apart. Observations and measurements were taken on 10 plants of each variety. Colours were determined using the 2001 Royal Horticultural Society (RHS) Colour Chart.
