Tests & Trials: Tests and trials for 'Evijohill' were established in the field during the spring of 2002, and observations and measurements were taken during the spring of 2003 at BioFlora, Inc., St. Thomas, Ontario. Eight rooted plants of the candidate and reference varieties were received April 20, 2002 and planted into 11.5cm pots and grown in a polyhouse. Young plants were transplanted to the field on June 3, 2002. Plants were spaced 60cm apart and trained to grow along a trellis. Observations and measurements were taken from 10 plant parts of each variety during June 2003. All colour measurements were made using the 2001 RHS Colour Chart.
