Tests & Trials: The test and trial for 'Robmornvan' was conducted during the summer of 2006 at Oxford Station, Ontario. Fifteen (15) plants of each variety were individually grown in 15 cm pots in a poly house. Plants were spaced 30 cm apart. Observations and measurements were taken on 10 plants of each variety. All colour measurements were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
