Tests & Trials: The comparative trial for 'ERFZ0001' was conducted in a polyhouse during the summer of 2015 at BioFlora Inc. in St. Thomas, Ontario. The trial included 20 plants each of the candidate and reference variety. All plants were grown from rooted cuttings transplanted into 15 cm pots on May 11, 2015. Observations and measurements were taken from 10 plants, or parts of plants, of each variety on July 14, 2015. All colour measurements were made using the 2007 Royal Horticultural Society colour chart.
