Selection criteria included variegated foliage, colour of newly opened leaves, slow growth rate and tolerance to foliage droop and twisting under cool growing conditions. Reproduction of the new variety by vegetative cuttings first began in May 2000.
Tests & Trials: The tests and trials for 'Inneuphhel' were conducted in a greenhouse at BioFlora Inc. in St. Thomas, Ontario during the summer of 2006. The trial included a total of 15 plants of both the candidate and reference varieties. All plants were grown from rooted cuttings and transplanted into 11 cm pots on May 10, 2006. Observations and measurements were taken from 10 plants of each variety on July 11, 2006. Observations on fall colours were made on October 30, 2006. All colour measurements were determined using the 2001 Royal Horticultural Society (RHS) Colour Chart.
