'Euro23' was selected on June 12, 2003 based on criteria for flower colour, compact plant growth habit, vigour, fast rooting and resistance to disease.

Tests & Trials: The test and trial for 'Euro23' was conducted in a polyhouse during the spring of 2006 at BioFlora Inc. in St. Thomas, Ontario. The trial included 15 plants of each variety. Rooted cuttings were transplanted into 15 cm pots on April 25, 2006. Observations and measurements were taken from 10 plants of each variety on June 9, 2006. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
