Tests & Trials: The trial for 'PERHC59B' was conducted in 2013 at Schenck's Greenhouses in St. Catharines, Ontario. The trial included 25 plants each of the candidate and reference variety. All plants were grown from rooted cuttings and transplanted into 15 cm pots on July 25, 2013. Pots were spaced 30 cm apart from the pot centre. Observations and measurements were taken from 10 plants of each variety on November 26, 2013. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
